The utility model principle:
Horizontal pendulum earthquake forecast instrument is from design angle and purpose, it mainly is the instrument of observing the movable energy of the preceding focus of shake, it has two kinds of functions, it is the instrument of a cover earthquake forecast, be again the bigger seismograph of a cover wavelength period, be mainly used to observe the also nonevent seismic activity incorrect energy that will take place.
The activity of horizontal direction and vertical direction can appear in geological formations before the earthquake, little slow activity is not only arranged, and the activity of geological formations has certain energy potential energy before the earthquake, and this activity is from the geological formations depths, has a kind of pressure impelling the activity of geological formations.Present large tracts of land deformation active state before the earthquake, facts have proved from the data of observing, the violent earthquake large deformation, the little deformation of small earthquake, meeting produces the low frequency " deformation waves " of suitable energy in deformation process.
The low frequency " deformation waves " that geological formations produces before the earthquake, its frequency is very low, thinks that tentatively per minute is in tens times to tens times fluctuation range.The time that this low frequency " deformation waves " occurs is very short, and the nearly dozens of minutes time, the time of Chu Xianing is shorter sometimes.
Epicentral area before violent earthquake takes place has the shaking phenomenon of horizontal direction and vertical direction to occur, and is exactly that a kind of low frequency " deformation waves " is outwards propagated in area far away.
Low frequency " deformation waves " acts on that forced vibration has a this phenomenon process from low to high on the horizontal pendulum, just says that also seismic event or low frequency " deformation waves " all are to begin forced vibration from corresponding pendulum length when arriving, and progressively rises to the reaction of short pendulum pendulum length.
At first we regard the length of the pendulum length of any one horizontal pendulum as and appoint justice a bit on the disc, with the radius length of pendulum length as disc.When this disc centered by the O point, begin to rotate any rotation speed per hour maximum of maximum radius at this moment, moment maximum under external force.And some speed per hour minimum forces of least radius are apart from also minimum.Therefore minimum radius a bit, at any time in from the rotation of positive and negative both direction, all less than any speed per hour of long pendulum radius.Disc when rotating or when stopping least radius a bit all be that rotate the back all the time, stop earlier.The radius of maximum pendulum length a bit rotates afterwards earlier and stops.Thereby external force acts on the time difference that has a concrete energy vibration to propagate on the horizontal pendulum.Ripple is that the form that a kind of physical quantity is exerted oneself shows, so the condition of the reaction of power and geometric configuration distance determines.
Low frequency " deformation waves " is to the reaction of effect from long pendulum to short pendulum of horizontal pendulum, be that a time and energy are apart from the relation of the forced vibration in cycle, explanation a bit is exactly that long pendulum arrives short pendulum under the effect of wave force again, wherein period frequency and corresponding cycle pendulum length begin incision accordingly one, this is the swing of the starting point of a pendulum length, the wavelength shape of " deformation waves " that transmits with the earth has substantial connection, has one to arrange swing to short pendulum pendulum length direction, and another is to the swing of long pendulum direction.This phenomenon all is to transmit a kind of wave force from the earth to act on performance on the horizontal pendulum.
Because the motion, particularly vertical movement of earth's crust block impel the top stratum that a kind of phenomenon of deformation takes place.Conveniently generally be divided into two kinds of VERTICAL DEFORMATION and horizontal deformation in order to observe.
Before the violent earthquake because the accumulation of terrestrial stress strengthens and concentrates, the epicentral area and in the neighbourhood geological formations ANOMALOUS VARIATIONS appears, finding has jumping phenomenon before violent earthquake takes place.This rapid variation is at ordinary times tens times, even bigger.Can occur temporarily stopping in some area or accelerate the gyration state in the other direction, become rapid decline or change the big abnormal occurrence of rapid rising from decline into from rising.This phenomenon generally takes place to occur in former hours to tens hours in violent earthquake, and the unusual back omen of sudden change occurring is exactly that violent earthquake (strong ruinous earthquake) will be arrived.The signal that means the reliable precognition that big shake will take place.Earthquake forecast particularly there is reliable important directive significance to prediction about imminent earthquakes.Geological formations deformation is undergone mutation before the violent earthquake, is the focus depths that seismic activity occurs in earthquake, expands earthward from the focus depths to form vertical direction to the underground pressure increasing on ground, impels ground direction geological formations deformation.
The anxious strong huge pressure of expansion generation will take place in the earthquake source depths before earthquake takes place, this pressure is direction expansion earthward in the depths, rock stratum, because after all directional pressure points increase to a certain degree, the surface geology rock stratum than any one direction to bear pressure capability all little, this is the breach of pressure, and the surficial geology rock stratum is held and be can't stand that this huge upwarding pressure only breaks to form earthquake and release energy.
In observation process, reacting phenomenon is a kind of, and the focus swelling pressure the weakest direction in rock stratum earthward break through, and this direction has the development space of relief pressure energy, and the surficial geology rock stratum is under pressure to increase will form upwards and rises.Progressively swelling for a kind of sensation the earth of observer, the situation of large tracts of land deformation shows as bulge.A speed that sharply expands is arranged, and to have a kind of rhythm be with the fluctuation unlifting pressure of per minute tens times to tens times the top stratum to be broken through in the pressure extrusion process.This phenomenon is one-period and semiperiod direction motion state earthward.What plutonic earthquake was reacted is holocyclic performance, and being exactly has the phenomenon characteristic that falls slightly after rise after focus pressure acts on top stratum appearance rising.Shallow-focus earthquake is just risen under the effect of focus pressure, stops, and rising is the semiperiod active state again.
Because the rock stratum expansion earthward of huge pressure, the every square metre of pressure that bears in rock stratum, ground has millions of tons to several ten million tons rock stratum extensional processes earthward according to a preliminary estimate.The moment that when earthquake takes place, releases energy, the pressure that bear the rock stratum, ground is above several one hundred ten thousand times even bigger, this phenomenon is not got rid of the reason that produce to expand in the earthquake source depths, and what have that other material has a fission under the high pressure-temperature certain conditions may play certain booster action (will volume increasing as the phreatic Temperature Influence that is subjected to).
According to the characteristic of the rectilinear propagation of this low frequency " deformation waves " that certain energy arranged, applicant's utility model this patent.
From a large amount of observational data statisticals, the amplitude anomaly angle of single pendulum does not surpass 3 degree before each earthquake.
The single pendulum formula:
It should be noted that:
1, horizontal pendulum involves zone observation seismic anomaly in earthquake, if there is the earthquake of suitable energy to take place simultaneously, horizontal pendulum just has certain amplitude of fluctuation, can be subjected to seismic event with horizontal pendulum observation seismic anomaly and disturb.
When 2, not having earthquake to take place, horizontal pendulum all is stationary state.
If 3 when not having earthquake to take place, directive swing appears in horizontal pendulum, and illustrate at the tangent line two ends of swing wherein has the area of a direction that the earthquake generation will be arranged.
4, behind the seismic anomaly that occurs, determine that if direction is bad illustrate with the earthquake centre more closely, earthquake is unusual, more stable relatively at a distance, and certain orientation is arranged.
5, the slow movable low frequency energy ripple seismograph of this geological formations does not observe.The slower activity of geological formations is not uniform active state, and has a kind of lower frequency properties energy waves and outwards propagate.
The swing of horizontal pendulum under periodic external force effect is forced vibration, forced vibration: be exactly a periodically amplitude process under the external force energy potential can act on of systematicness.
The amplitude state amount of horizontal pendulum forced vibration: be the period frequency of wave force and the intrinsic cycle of horizontal pendulum to differ more big, endergonic effect is just more low from the external world in system, and the amplitude state amount that horizontal pendulum is done forced vibration is just more little.The intrinsic cycle of the period frequency of wave force and horizontal pendulum differs more little, and endergonic effect is just more high from the external world, and the amplitude state amount that horizontal pendulum is done forced vibration just increases.When the period frequency of wave force was identical with the intrinsic cycle of horizontal pendulum, the amplitude state amount of horizontal pendulum forced vibration was just maximum, and this moment, the effect of absorption of energy was just the highest.Resonance: the amplitude state amount of forced vibration was just more big when the period frequency of wave force equaled natural period of horizontal pendulum, and this phenomenon is called resonance.T
Fluctuation=T
Intrinsic, (f
Fluctuation=f
Intrinsic).
Horizontal pendulum is got rid of all artificial interference and environmental interference under static state, horizontal pendulum can unprovokedly not swung.The wave force that transmitted from the external world by the earth just has corresponding dancing.
The subterranean strata depths of seismic zone before earthquake takes place, the earthquake source pressure expansion acts on vertically upward, and rock stratum, ground direction is caused the earth deformation, can produce a kind of lower low frequency " ripple ", now this ripple is called low frequency " deformation waves ".The energy of " deformation waves " is very little, and the time that " deformation waves " occurs does not have regularity, and only the geological formations of seismic zone occurs before earthquake, because measuring point is the fixed position, the zone of earthquake is also changing in continuous variable in distance.So just there is not fixing period frequency, just act on a kind of driving phenomenon on the horizontal pendulum, this low frequency " deformation waves " has certain energy potential energy, when this energy potential energy occurs again and again be superimposed upon on the horizontal pendulum swing that drives horizontal pendulum, appear at every turn and arrange swing on natural period of horizontal pendulum from low to high, " deformation waves " does the phenomenon that drives the horizontal pendulum swing from long pendulum to short pendulum is progressively to rise, and a ripple time intrinsic cycle of rising needs about 10 minutes, and the time is not waited.Under the state of resonance, the period frequency of " deformation waves " no longer rises on the intrinsic cycle at horizontal pendulum, is single single pendulum performance, horizontal pendulum resonance state amount maximum at this moment, and this is a remote violent earthquake abnormal occurrence.
The swing of horizontal pendulum all is progressively to be increased to maximum corresponding displacement from equilibrium state at every turn, is not with regard to swing (swing suddenly only is subjected to seismic event in earthquake driving just can have this phenomenon).To a horizontal pendulum, be increased to a natural amplitude gradually from 0.00mm to tens mm, after reaching current energy maximal value, weaken gradually again and decay and, reply static substantially equilibrium state at last, this is an exception procedure with energy, and the amplitude size that acts on the horizontal pendulum is directly proportional with releasing energy of earthquake of generation.Calculate the energy grade that earthquake release will take place according to the big I of amplitude.
The earthquake prediction principle:
1, three-point fox method: referring to Fig. 5, known: violent earthquake appears in each observation station all a resonance cycle pendulum length when unusual simultaneously, utilize intrinsic cycle scaled distance location, AD, BD, CD, the observation station resonance cycle wavelength that equals each department also equal the unit ratio length of horizontal pendulum.
1 is that radius is drawn arc and intersected at the D point at map with A for initial point AD length.
2 is that radius is drawn arc and intersected at the D point at map with B for initial point BD length.
3 is that radius is drawn arc and intersected at the D point at map with C for initial point CD length.
Three arcs intersect at the D point, Here it is seismic activity zone, and earthquake will occur in this area.
2, seismic anomaly single pendulum swaying direction three-point fox method:
Referring to Fig. 6, prolong through amplifying to handle with single pendulum displacement amplitude direction, A, B, three observation stations of C are drawn three and are prolonged crossing 1 D of ray location.Going up picture projection tangent line by (terrestrial globe is the earthquake orientator) realizes.Because our earth surface is not a desirable desktop, according to ripple the rectilinear propagation characteristic is arranged.Ripple is that the along continuous straight runs propagation is main path on earth, finishes so upward must draw tangent line at map (earth).
3, velocity of wave time difference three-point fox method: be bee-line in rectilinear propagation according to ripple:
Referring to Fig. 7, the time that " deformation waves " propagates into the measuring point of A is 12: 18: 30 on the 12nd September in 2012.The time that " deformation waves " propagates into the measuring point of B is 12: 18: 30 on the 12nd September in 2012.Because 2 velocity of wave time differences of AB equate, can make perpendicular bisector 2 of AB, " deformation waves " propagates into the time that C orders is 12: 18: 45 on the 12nd September in 2012, can deduct velocity of wave mean value (velocity of wave average out to 1km/S) by the wave propagation time difference at the C point, displacement amplitude direction with single pendulum, on the displacement straight line of single pendulum, move 15km (map scale 1Cm equals 60 kilometers) to the AB rectilinear direction, be that the garden heart is that radius is drawn the garden with the velocity of wave difference with C, EF is that particle displacement amplitude of oscillation direction is geological formations activity energy state amount, EC is that distance is the time difference of ripple, this E point equates with the velocity of wave time difference that B is ordered, and can intersect at the D point at the perpendicular bisector that E point and two of B points are made perpendicular bisector and AB.Here it is seismic anomaly zone of action, the area that earthquake will take place.
The earthquake forecast three elements:
1, where earthquake takes place: horizontal pendulum earthquake forecast instrument; Record the earthquake centre of the earthquake that will take place just on this tested straight line.
2, the intensity earthquake magnitude of earthquake has much: horizontal pendulum earthquake forecast instrument; The earthquake magnitude that records the earthquake that anomalous amplitude will take place is the n level.
3, when earthquake taking place: generally forecasts back 6 hours to a week from sending.
About the matter of time of earthquake takes place: be a supposition with practical experience, the time that earthquake will take place, depend on the structure quality of the geological formations of seismic zone.To earthquake takes place, depend on earthquake source pressure energy speed of expansion from unusually, have a regular time to distribute, the time of short ground generation earthquake is generally all in 24 hours.Elasticity rock stratum quality is high, and the time of earthquake generation is compared with short ground with the time that occurs unusually and wants the many of evening, is a week from the unusual time to the generation earthquake occurring.Most of earthquakes all occurred within 3 days, and the minority earthquake occurred within 6 days, and the area that new earthquake does not take place does not extremely individually have under the influence of other shake, and special geological structure also has 10 days time that the situation of earthquake takes place.
All satisfied from the three elements condition of earthquake prediction, so the just generation of prediction earthquake that can be correct.
