Description

Utilize the dust-proof wall of seismic wave of the Resonant Column of burying

Technical field

The present invention relates generally to a kind of for the protection of the antishock device of building free by earthquake effect; relate more specifically to a kind of technology for the protection of the building outside antidetonation barrier or earthquake shadow region; this technology by burying many Resonant Columns thus stop earthquake wave propagation as antidetonation barrier or earthquake shadow region outside building, instead of installs antishock device in building itself.

Background technology

Earthquake is the one in inevitable typical natural calamity, and to property, the most important thing is that the resident to those are lived near earthquake zone or earthquake zone threatens.In order to reduce the destruction that earthquake causes, carry out the much research about Antiseismic building design (comprising early earthquake warning system).Therefore, quite effectively prevent the resident lived near earthquake zone or earthquake zone and be subject to earthquake effect.

But still there is thousands of people killed or wounded in earthquake in the annual whole world.The earthquake occurring in the east coast of island, Japanese Honshu celestial platform in recent years on March 11st, 2011 describes no matter how outstanding seismic design is, and building is safety never and is not subject to the impact of earthquake risk.

Existing anti-seismic construction method is the anti-seismic technology adopting such as antidetonation, shock insulation and damping etc. when initial construction of buildings for building itself.But these anti-seismic construction methods should provide separately to each building, and therefore cost is very high.Therefore, should provide one independently method, the method can architecture protection group or obviously improve even be protected for the antidetonation of the building built before.

The present invention relates to a kind of method reducing seismic damage, this method is based on the novel designs being different from existing Traditional method of seismic design completely.Existing method is the point protection each building being carried out to independent protective after seismic wave arrives building; and method of the present invention is locality protection method, the method premature discontinuation seismic wave and protect a panel region before seismic wave arrives one or more building.For this reason, the Resonant Column corresponding to frequency of seismic wave is buried on the path of seismic wave.This structure absorbs seismic wave at seismic wave through Resonant Column and prevents stronger seismic wave from arriving building.This effect of the present invention is to utilize the principle of the acoustical material of institute of academia active research in recent years.

Seismic wave is a kind of sound wave essentially.At all sound waves after Resonant Column, the sound wave close to resonance frequency is absorbed, and can not pass through these structures.This principle is from acoustical material.But, also acoustical material principle is not applied to the example of the technology preventing seismic damage so far.

Summary of the invention

Technical problem

Existing seismic design architecture protection thing itself.This design is associated with the basic structure of building, and produces a lot of expense when therefore the building of construction is to improve its shock resistance before seismic design being applied to.Particularly, once the existing building of such as atomic power plant or steel mill completes and comes into operation, be then difficult to change seismic design and improve its shock resistance.

Therefore; the present invention has considered the problems referred to above in association area; and intend, by the mode of burying Resonant Column at Around Buildings, anti-vibration barrier is installed; and jointly protect owned building, be embedded with the antidetonation barrier that can weaken seismic wave before seismic wave arrives building at these Around Buildings.

Technical scheme

The invention provides a kind of antidetonation barrier (150) by being buried and be deposited in underground and formed by many Resonant Columns (100), wherein each Resonant Column is closed by the barrier portion of plane (1) or bending barrier portion (2) to form internal cavity, and at least one in the barrier portion of plane or bending barrier portion has at least one through portion (10) for being communicated with from containment portion with cavity.The shape of antidetonation barrier can be circular, semicircle and rod etc., and with treat protected Region Matching.

The inductance capacitance LC oscillator of electrical engineering is implemented as mechanical LC oscillator by Resonant Column.The energy of seismic wave advances through Resonant Column, and is converted to acoustic energy and heat energy.Therefore, when seismic wave is through many Resonant Columns, the earthquake magnitude of seismic wave exponentially reduces suddenly.

Along with the width of earthquake barrier increases, add the minimizing degree of the earthquake magnitude of seismic wave.When the ripple that shakes of seismic wave is identified as 3 grades on the basis of Li Xite scale, the width of earthquake barrier as shown in equation 10, should be similar to the wavelength of seismic wave.The wavelength of seismic wave is not constant, but usually can be approximately 100m.

The quantity of Resonant Column is determined according to the length of earthquake barrier.As shown in Figure 8, there occurs diffraction phenomena, wherein seismic wave bends in an end of earthquake barrier.Therefore, when earthquake barrier length should also long than the wavelength of seismic wave time, broaden shielded region.

Resonant Column (100) can have cylindrical shape, hexahedral shape, octahedra shape or spherical form.The resonance frequency of Resonant Column and the resonance frequency of seismic wave match, and by three because usually determining, i.e. the area of through portion of the internal volume of Resonant Column, the entrance of Resonant Column and the length of through portion, and have nothing to do with the shape of Resonant Column.Area along with entrance becomes larger, and internal volume becomes less, and the length of through portion becomes shorter, and high-frequency is blocked.When there is multiple through portion, the combination that the series and parallel connections that Resonant Column follows circuit connects.

When Resonant Column as shown in Figure 5 and Figure 6, when carrying out burying and stacking in the modes of 4 row 4 row, the space of inner sky is used as capacitor, and therefore how the shape of Resonant Column should be all empty.The through portion of each Resonant Column is towards the space perforate of this sky, and therefore Resonant Column interconnects by means of through portion.

Because seismic wave is the ripple being mixed with different frequency, therefore have that multiple Resonant Columns of different resonant frequencies are mixed makes its through portion interconnect as the connection of component in a vertical and horizontal direction with being piled into.

If have 5 through portion perforate in the Resonant Column with about 30cm thickness of about 50cm diameter, then the volume of a Resonant Column (100) is depending on the wavelength of seismic wave, can be in from 1.0m ³to 100m ³scope in.

Resonant Column (100) can be buried in underground, and the height of a distance Resonant Column is in the scope from 1m to 100m, and this scope is the degree of depth or the earthquake wave frequency of foundation engineering.

Advantageous effects

According to utilizing the antidetonation barrier of Resonant Column of burying, building not by independent protective, but with seismic wave isolator on predicted path antidetonation barrier being arranged on seismic wave.Therefore, an area is by Global Macros.By the width of adjustment refractive index and antidetonation barrier, the earthquake intensity passing to building can be reduced to desired level.

Different from the design changing building itself, antidetonation barrier is arranged on Around Buildings.Thus, before seismic wave arrives building, seismic wave is weakened.Therefore, the building that antidetonation barrier is built before can being effectively applied to.Therefore, there is no need for the measure of the seismic design changing building itself.

Detailed description of the invention

Below with reference to accompanying drawings the preferred embodiment of the present invention is specifically described.But these embodiments are below provided to allow those skilled in the art to fully understand and can carry out various amendment to these embodiments.Scope of the present invention is not restricted to embodiment described herein.In whole accompanying drawing, identical Reference numeral is used to refer to same or similar parts.

Seismic wave is a kind of sound wave, and by as just (P) ripple of bulk wave and time (s) ripple and as Rayleigh (R) ripple of ground roll and Loew (L) wave component.In addition, the different wave length right and wrong of ripple are mixed uniformly.In these ripples, R ripple and L ripple damage building.

The reason that R ripple and L ripple are called as ground roll is, these ripples exist only in the degree of depth being equivalent to about 1 wavelength with surface apart, and exponentially reduces suddenly when exceeding the degree of depth being equivalent to an about wavelength.Ground roll has much slower than bulk wave speed, and more uneven than bulk wave, and has speed, 30Hz or the less frequency and 100m or shorter wavelength that are approximately 1 to 3km/sec.Therefore ground roll is almost left in the basket at the depth of 1.5 times of wavelength of 150m or more.

All sound waves have the determined speed of ratio by density and modulus of elasticity.Modulus of elasticity is divided into three classes according to applied dimension, is namely applied to the young's modulus of elasticity of one dimension, is applied to the modulus of shearing of two dimension and is applied to three-dimensional bulk modulus.Modulus of shearing can be treated as special circumstances, and one of them plane is fixed on bulk modulus place.Ground roll is two-dimentional ripple from macroscopic perspective, is three-dimensional wave from microcosmic angle.

All sound wave propagation velocities are determined by the density of the medium of equation 1 and elastic modulus G.When sound wave is through Resonant Column, do not have the specific frequency field of ripple near the frequency field corresponding to Resonant Column to propagate, reason is as follows.

Usually, when applying pressure to object, object is compressed.The ability of opposing compression is modulus of elasticity.Because volume when the pressure is exerted reduces, therefore modulus of elasticity normally on the occasion of.As fruit volume opposing external pressure expands, then modulus of elasticity becomes negative value.When the air in wave direction Resonant Column is exerted pressure, the ripple in Resonant Column is superposed on one another, and constructive interference occurs, to produce the effect that the air in Resonant Column expands on the contrary.The modulus of elasticity frequency field become residing for negative value is the region of the resonance frequency from such as equation 4 to a frequency a little more than this resonance frequency.

When modulus of elasticity becomes negative value due to resonance, velocity of wave becomes imaginary number according to equation 1.When velocity of wave becomes imaginary number, refractive index n and wave vector also become imaginary number as shown in equation 5 and 6, and therefore the earthquake magnitude of ripple exponentially reduces.This and following principle equity, that is, when applying air pressure by musical instrument mouthpiece to wind instrument, resonates, and pressure energy changes into acoustic energy in wind instrument.When the earthquake magnitude of ripple exponentially reduces, then ripple disappears, and does not propagate.

Again will be described with mathematical way below.Earthquake wave propagation velocity is confirmed as the square root of the ratio of density p and elastic modulus G by equation 1.

Equation 1

$v=\sqrt{G/\mathrm{\ρ}}$

When elastic modulus G becomes negative value, speed v becomes imaginary number.The refractive index n proportional with the inverse of speed becomes imaginary number according to equation 2.

Equation 2

$n=\frac{c}{v}$

In equation 2, n represents refractive index, and c represents the background velocity of sound wave.When elastic modulus G becomes negative value, refractive index n and wave vector become imaginary number, and this ripple disappears.The physical quantity of this imaginary number is the concept of Meta Materials.This Meta Materials refers to so a kind of material, that be not observed before this material has or be difficult to electromagnetic material or the acoustical material realized by traditional material response.

Fig. 1 shows a kind of structure of the Resonant Column successfully realizing in test the modulus of elasticity born and corresponds to the lc circuit of this structure.

The structure with the Resonant Column 100 of negative modulus of elasticity has main body, and the plane of this main body is sealed and be formed with through portion 10 in a plane of this main body.If there is multiple through portion, then these through portion follow the combination that series and parallel connections connects.

When the buildup of pressure of the sound wave through through portion 10 is in cavity 30, and when there is resonance, the air pressure expansion caused by sound wave, and modulus of elasticity becomes negative value.This is the principle of acoustic metamaterial.

Fig. 2 is the curve map for equation 3, and wherein, when multiple Resonant Column coupled in series, frequency w is set to independent variable, and the real part of modulus of elasticity (solid line) and imaginary part (dotted line) are set to dependent variable.This graph illustrate the elastic modulus G of material _effhow to change according to frequency w.

Equation 3

$\frac{1}{G_{\mathrm{eff}}}=\frac{1}{G_o}[1-\frac{F{w_o}^2}{w^2-{w_o}^2+\mathrm{i\Γw}}]$

In equation 3, F is combination (that is, the interval between Resonant Column or the layout of Resonant Column) according to Resonant Column and by testing the geometrical factor determined, and is fissipation factor.When the Resonant Column be connected increases, the value of F increases, and the region that the real part of modulus of elasticity becomes residing for negative value increases.When fissipation factor is very little, the frequency field that the real part of modulus of elasticity becomes residing for negative value can be presented scope as shown in equation 4.

Equation 4

$w_0<w<\sqrt{1+F}{w}_0$

In equation 4, W ₀it is the resonance frequency of Resonant Column 100.

When there is resonance, the effect that seismic wave reduces produces from resonance frequency to the region of the given frequency higher than resonance frequency.Seismic wave is non uniform wave, and its frequency great majority are 1 to 30Hz.Therefore, the scope from 1 to 30Hz is preferably set to according to the resonance frequency range of Resonant Column of the present invention.

With reference to Fig. 2, the real part region become residing for negative value of modulus of elasticity resonance occurs and the wave vector of sound becomes region residing for imaginary number.The imaginary part in this region becomes negative value.When imaginary part becomes negative value, energy is absorbed.

Absorbed energy is converted to heat energy and acoustic energy in Resonant Column 100.Suppose that absorbed energy is converted to acoustic energy completely, then intensity of sound can find in equation 15.

According to equation 2, the refractive index of medium is presented as the inverse of ripple speed V in media as well.That is, G is worked as _effwhen specific frequency field becomes negative value, refractive index n becomes imaginary number, and refractive index can represent as in equation 5.

Equation 5

$n=i\left|n\right|$

The ground roll of such as L ripple and R ripple adopts the form of the plane wave obtained by the product of earthquake magnitude and SIN function.When the direct of travel of ground roll is X-direction, and when refractive index is imaginary number, wave equation can be represented by equation 6.

Equation 6

$A{e}^{\mathrm{ikx}}=A{e}^{\frac{i2\mathrm{\&pi;nx}}{\mathrm{\&lambda;}}}=A{e}^{\frac{-2\mathrm{\&pi;}\left|n\right|x}{\mathrm{\&lambda;}}}$

According to equation 6, when ground roll is advanced, namely when x increases, the earthquake magnitude of ripple exponentially disappears.

At this, the magnitude M according to Li Xite scale can represent as equation 7.

Equation 7

$M=\log \frac{A}{A_0}$

In equation 7, A is in the seismic wave largest magnitude measured apart from the position of earthquake centre 100km, A ₀be the largest magnitude of the background wave when not having earthquake to occur, and be set to 1 m (10 ^-6m).

When seismic wave is through the antidetonation barrier as earthquake barrier, the earthquake magnitude of sound wave is reduced as shown in equation 8.

Equation 8

$A_i{e}^{\frac{-2\mathrm{\&pi;}\left|n\right|x}{\mathrm{\&lambda;}}}=A_j$

When the initial earthquake magnitude of seismic wave before Resonant Column is defined as M _i, and the final earthquake magnitude of seismic wave after Resonant Column is defined as M _ftime, equation 8 is presented as shown in equation 9.

Equation 9

$A_o{10}^{\mathrm{Mi}}{e}^{\frac{-2\mathrm{\&pi;}\left|n\right|x}{\mathrm{\&lambda;}}}=A_o{10}^{\mathrm{Mi}}$

Difference between initial earthquake magnitude and final earthquake magnitude is given M=M _f– M _itime, the x-axis Distance geometry width X of antidetonation barrier _cobtain as shown in equation 10.

Equation 10

$x_c=\frac{\ln 10}{2\mathrm{\&pi;}}\frac{\mathrm{\&lambda;\&Delta;M}}{\left|n\right|}=\frac{0.336\mathrm{\&lambda;}}{\left|n\right|}\mathrm{\&Delta;M}$

As what can find out from equation 10 above, the width X of antidetonation barrier _cproportional with the wavelength of seismic wave, and be inversely proportional to the refractive index n of antidetonation barrier.Therefore, when Resonant Column is made up of the cement concrete with very high refractive index, the width of antidetonation barrier can reduce.The refractive index of antidetonation barrier is determined by the refractive index of Resonant Column and the space material around it, and the approximate refractive index being similar to Resonant Column.M intends weakening the magnitude difference entering the seismic wave of antidetonation barrier.

The wavelength of seismic wave is mainly in the scope of 50 to 200m.The refractive index of cement concrete is mainly from the scope of 1 to 2.The width X of antidetonation barrier _cneed in the scope of 8 to 67m to reduce earthquake magnitude 1.Consider safety factor, the width of shockproof barrier is mounted to long limit, and is preferably set to the scope from 20 to 100m, to reduce earthquake magnitude 1.

Such as, assuming that want seismic wave to be reduced to earthquake magnitude 3 from earthquake magnitude 6, then M is 3.Suppose that the wavelength of seismic wave is large when building the antidetonation barrier for reducing earthquake magnitude 3 in this case, the width X of antidetonation barrier _cbeing 110m when refractive index is approximately 1, when refractive index is approximately 2, is about 55m, as shown in equation 11.

Equation 11

$x_c=\frac{36.6X3}{2}\&cong;55\left(m\right)$

Now, the resonance frequency of Resonant Column obtains as described by the structure of Resonant Column.With reference to Fig. 1, the narrowing portion 15 of through portion 10 corresponds to the inductor of lc circuit, and the cavity 30 in Resonant Column 100 corresponds to the capacitor in lc circuit.In order to represent inductor and capacitor, the left side of Fig. 1 illustrates when representing with electrical way, and Resonant Column can be presented as the series circuit of inductor and capacitor.The electric capacity of capacitor follows equation 12, and the inductance of inductor follows equation 13.

Equation 12

$C=\frac{V}{\mathrm{\&rho;}{v}^2}$

Equation 13

$L=\mathrm{\&rho;}\left(\frac{L^{\&prime;}}{S}\right)$

?

At this, V is the volume of Resonant Column 100, be the density of the medium (air) in Resonant Column, and v is background velocity.L ' is the effective length of the narrowing portion 15 of through portion 10, and S is the cross sectional area of the entrance of through portion 10.Effective length is that the radius of the entrance of through portion is added with the thickness of through portion the value obtained.When the entrance of through portion is not circle, its radius is the radius when its area is equivalent to circle.

At this, the resonance frequency of the Resonant Column 100 of Fig. 3 ₀follow equation 14.

Equation 14

${\mathrm{\&omega;}}_o=\frac{1}{\sqrt{\mathrm{LC}}}=\sqrt{\frac{S}{L^{\&prime;}V}}\mathrm{\&upsi;}$

The resonance frequency of equation 14 is the resonance frequencies obtained by equation 1 and 13.

In equation 14, v is background velocity.According to equation 14, the resonance frequency of Resonant Column 100 depends on the structure of Resonant Column 100.That is, when the effective length L ' of the through portion 10 of perforate in Resonant Column 10 becomes longer, when the entrance cross-section area S of through portion becomes narrower, and when the volume in Resonant Column becomes larger, Resonant Column is with lower frequency resonance.

Equation 15

When seismic wave is converted to sound and Re Shi at antidetonation barrier place hypothetically, and when being only reformed completely into sound, the intensity of sound represents with decibel.In equation 15, M is the earthquake magnitude of the seismic wave of the determination of seismic wave on the basis of Li Xite scale, and b is the constant obtained by test, is approximately 1.5.D is for representing the distance in distance earthquake centre, and unit is km (reference paper 1 and 2 with reference to below).

Embodiment

First, the Resonant Column 100 as the elementary cell of antidetonation barrier is manufactured.As in equation 10, the width of antidetonation barrier and the refractive index of antidetonation barrier are inversely proportional to.Therefore, when Resonant Column is made up of the material with high index, the width of antidetonation barrier can be reduced further.

Fig. 3 is schematic diagram, shows the shape of the cylindrical Resonant Column in the upper side and lower side according to the present invention with through portion.

In addition, the buried residing degree of depth of Resonant Column 100 preferably equals or is deeper than the foundation engineering of building.But, do not need darker than the wavelength length of 100m.

The volume V of a buried Resonant Column for antidetonation barrier depends on earthquake wave frequency, and is set at from 1 to 100m ³scope in.The width Xc of antidetonation barrier can be mated and be adjusted to required antidetonation level.

Fig. 8 is top view, shows the antidetonation barrier protection building free of Resonant Column that utilizes according to the present invention by the scope of the plane of earthquake effect.Due to the vortex phenomenon of seismic wave, the region residing for seismic wave of partial penetration occurs between shielded plane and not protected plane.Therefore, the protection for the subregion residing for seismic wave infiltration may not be enough.

The antidetonation barrier formed by Resonant Column 100 is buried in underground, and does not occur in outside.

When considering that submarine earthquake arrives land in unencumbered situation, the antidetonation screen effect of installing by ditching and by the mode that water fills up is little.
