Technical field
The present invention relates to civil engineering, hydraulic engineering, mechanical engineering field, particularly a kind of be used for the aqueduct structure laterally subtract the shock insulation mixed control apparatus.
Background technology
Found the state over more than 60 year, though the water conservancy construction of China has been obtained prominent achievement, the form that faces is still quite sternly completed: the one, and water pollutes with water environment and worsens day by day; The 2nd, the water resource critical shortage; The 3rd, flood and do that early disaster is frequent.Along with the development in an all-round way of economic society, it is complicated and severe more that the water resources problems of Future in China will seem, in a lot of fields and many areas, water problems has become the primary restraining factors of economic development.
Aqueduct is a kind of important hydraulic structure, and its main effect is to carry ditch water flow to cross over river, road, mountain valley, has a wide range of applications in China various places.Spell out in " hydraulic structure earthquake resistant design code " explanation of compilation before China: " hydraulic structure such as aqueduct; owing to lack dynamic characteristics data and practice experience; can't in this standard, summarize; await further stockpile; when revising from now on, progressively replenish (referring to document: Ministry of Water Resources of the People's Republic of China's " hydraulic structure earthquake resistant design code " is [S] (SDJ10-78); Beijing hydraulic and electric engineering publishing house, 1978 years) ".But still do not mention in " the hydraulic structure earthquake resistant design code " of new promulgation the aqueduct this respect content (referring to document: Ministry of Water Resources of the People's Republic of China. " hydraulic structure earthquake resistant design code " be [S] (DL5073-2000). Beijing hydraulic and electric engineering publishing house, 2000), the pertinent literature that can consult is also less, thereby makes present China aqueduct seismic design still have no laws to follow.From the antidetonation angle, the main difference of aqueduct and bridge is the form of structure of water body formation " top-heavy " in the huge tank, and this form of structure is extremely unfavorable to antidetonation.China is one of country that earthquake disaster is the most serious in the world, and earthquake zone is widely distributed, and the antidetonation of building is very important.When aqueduct passed through the earthquake zone, the safety problem of these aqueducts under geological process was the significant problem that is related to national economy and the people's livelihood.Because no matter the particularity of this class formation is theoretical research, still design experiences famine all, its earthquake safety problem is the focus of hydro-structure antidetonation field concern always, becomes the important topic that hydro-structure antidetonation field needs to be resolved hurrily.

Described grille cloth places in the middle of the aqueduct cross section, and is the same with the aqueduct span long.
The present invention has broken through existing aqueduct structure and has laterally subtracted the bottleneck of shock insulation aspect and remedied the deficiency that aqueduct laterally subtracts the shock insulation research and design, compared with prior art has following major advantage:
(1) gives full play to the effect of quality water body greatly in the cell body, consider the TLD effect of water body, utilize rocking of water body to reduce the seismic response of aqueduct, thereby become the unfavorable of water body, break through the big quality water body of tradition the disadvantageous research method of aqueduct structural seismic into favourable.
(2) install simply, economical and practical.The installation of grid, damper, spring and plumbous zinc neoprene bearing all only needs to carry out on the aqueduct structure, and its installation is simple, and extra charge is less relatively.
(3) it is good to subtract isolating affection.Existing aqueduct subtracts shock insulation research and mainly concentrates on the analyzing and processing of water body and installing of bearing, and method is single, DeGrain.This device bases oneself upon existing ripe structure Passive Control theory, by the measure of additional grid, plumbous zinc neoprene bearing, damper and spring, reaches the purpose that significantly reduces the response of aqueduct structure lateral seismic.
For supporting above-mentioned advantage, the spy provides data and the analysis result of doing correlative study.
The aqueduct total length 445m of certain large-sized aqueduct, 280 meters of groove figures are freely supported structure, the long 40m of single span, cell body overall width 12m.The site category at engineering place is the II class, and fortification intensity is 7 degree.The groove pier adopts solid pier body, groove pier height 15m, and the groove socle is wide to be 13.2m, and groove pier bottom is wide to be 19m, and basic elevation is 60.25m, and each is supported on the aqueduct body both ends on the groove pier with 2 benzvalene form lead core rubber supports.For this project need primary study be in the centre along the vertical elongated aqueduct type that adds grid of aqueduct, be the monolithic stability that guarantees grid, adopt the experience way in the relevant aqueduct design, longitudinally establish a pull-rod spring and the both sides cell wall sockets every 4m.This project utilizes the Ansys finite element analysis software to wherein one striding it is studied.This project is according to the influence of the correlative factors such as site condition at engineering place, chooses true macroseism record EI-Centro(N-S commonly used) ripple carries out time-history analysis to the aqueduct structure.Amplitude is adjusted into the amplitude of 8 degree rarely occurred earthquakes (400gal), and time step is apart from being taken as 0.02s, and the duration is 15s.Guaranteeing that water amount equates that (cross sectional area is constant to be 72m 2) prerequisite under, get aqueduct depth-width ratio H/B be respectively 1/3,1/2 and 2/3 3 kind of operating mode calculate, and emphasis is analyzed the lateral displacement at control point, span centre cell wall top and the moment of flexure at span centre cell wall root control point, and Fig. 1,2 is the seismic response comparing result of aqueduct structure.
By analyzing as can be known:
(1) the additional mass model is considered as rigid body with water, and quality all appends on the cell body, seriously the earthquake inertia force effect of exaggerative water body; The relative dead slot of additional mass model, the maximum amplification of displacement reaches 188.03%, and the maximum amplification of transverse bending moment reaches 160.50%; This explanation: it is not right that aqueduct water is considered as rigid body!
(2) under geological process, the aqueduct water body has tangible TLD effect, compares the additional mass model, and the effect of rocking of water body can obviously reduce the earthquake response of aqueduct.Single groove TLD model is compared the additional mass model, and the maximum range of decrease of displacement can reach 44.99%, and the maximum range of decrease of moment of flexure also can reach 38.55%.After adding grid and spring, the TLD control of water body is compared the additional mass model and is further increased, and the displacement maximum decreases by 55.74%, and the maximum range of decrease of moment of flexure is 47.50%.
(3) referring to Fig. 1 and Fig. 2, by the comparative analysis of each operating mode, along with the increase of aqueduct depth-width ratio H/B, the relevant parameter of each computation model almost all increases thereupon, and the seismic response of promptly corresponding each aqueduct computation model of operating mode amplifies thereupon.Can draw thus, under the prerequisite of same water amount, H/B is more little for aqueduct body, and seismic response is corresponding to be reduced, but the damping effect of water body is best when H/B=1/2.Symbol among Fig. 1 and Fig. 2 is respectively: the empty aqueduct model of A.; B. additional mass model; C. single groove TLD model; D. dividing plate TLD model; S. displacement; M. moment of flexure.
(4) the relatively lateral seismic of dead slot model and grid, spring, the identical operating mode of TLD model response, the former every dynamic response index is nearly all less than the latter, this is variant with structure TLD Passive Control effect, the water body that big quality is described has certain influence to the aqueduct seismic response, should consider the effect of water body when therefore carrying out the aqueduct seismic design.

The specific embodiment
After the present invention is based on the horizontal earthquake research of aqueduct of aqueduct water body TLD effect, what the aqueduct structure was provided laterally subtracts the shock insulation mixed control apparatus, this device is used for the structure design of large-sized aqueduct structure and has built the reinforcing and the reparation of aqueduct structure, its structure as shown in Figure 3 and Figure 4, mainly form by damper 1, spring 2, grid 4 and plumbous zinc neoprene bearing 6, wherein: damper 1 and spring 2 are provided with a plurality of, they along aqueduct longitudinally to being provided with between aqueduct wall 3 tops, both sides.Grid 4 is along vertically arranging in the aqueduct groove.Plumbous zinc neoprene bearing 6 is installed in the top of groove pier.Aqueduct water body and cell body self constitutes rectangle TLD large water tank.
The effect of described damper 1 and spring 2 mainly is the seismic response that reduces aqueduct wall top, because the seismic response at cell wall top is maximum relatively, so damper is set and spring can finely address this problem.
Connecting portion at the top of aqueduct wall 3 and damper 1, spring 2 is provided with stiffening rib, to strengthen and being connected of aqueduct wall.Grid 4 positions are set in aqueduct set up vertical concrete pillar 7, damper 1, spring 2 one ends are linked to each other with pillar, the other end links to each other with aqueduct wall 3; Pillar and cell body are cast-in-place to be whole, to strengthen its integral rigidity.
Described grid 4 based on the theory of structure Passive Control, utilizes big quality water body in the groove, further brings into play the TLD effect; Because the damping effect of TLD is relevant with multiple factors such as viscosity, frequency and sizes, therefore for the horizontal damping effect that increases water body along vertically arranging grid in the aqueduct groove, with the horizontal damping of increase water body, thereby the rolling power of increase water body makes that the lateral seismic response of groove body is reduced.When grid 4 is vertically arranged in the aqueduct groove, can be optimized design to its arrangement, be transferred to the cycle of oscillation of water body in the aqueduct near the natural vibration period of aqueduct structure, to such an extent as to can make the water in the aqueduct agitate the generation breaking wave, obtain maximum flowing pressure, thereby reach optimum effectiveness in vibration suppression.
Described plumbous zinc neoprene bearing 6 can be made by plumbous zinc rubber, plays function of shock insulation.Because geological process mainly is from the past cell body that is uploaded to of aqueduct pier, therefore at aqueduct pier top described plumbous zinc neoprene bearing 6 is set, and can further reduce the geological process of earthquake to the top cell body, thereby reduce the geological process of whole cell body greatly.
Described TLD, promptly aqueduct and water body form tuned liquid damper, TLD, tuned sloshing damper, and itself just can play cushioning effect; Act on the aqueduct as additional mass but water body is considered as rigid body, this does not meet the aqueduct actual condition of structure with regard to exaggerated the seismic response of aqueduct unilaterally.
From as can be seen last, this device has been opened up new thinking for the shock insulation research of subtracting of aqueduct structure, and the safety issue of aqueduct structure in can fine solution earthquake.
The present invention is through after the above-mentioned measure, make grid 4 and damper 1, spring 2 and plumbous zinc neoprene bearing 6 reach four optimum organization, final formation aqueduct TLD, grid 4, damper 1, spring 2 are controlled with the vibrations that mix of plumbous zinc neoprene bearing 6, thereby fully reduce the seismic response of aqueduct superstructure, promptly reach and mix the control effect.
Aqueduct structure provided by the invention laterally subtract the shock insulation mixed control apparatus, its course of work is: when earthquake is arrived, the inertia force (being geological process) that earthquake produces is through the plumbous zinc neoprene bearing 6 of lead-over groove Dun Ding, consumed portion of energy by it, promptly make the inertia force that passes to the aqueduct superstructure reduce; This inertia force rocks the aqueduct water body, and water body produces the cushioning effect of TLD, and grid 4 increases the damping of TLD simultaneously, thereby further reduces the aqueduct vibrations; Since the vibrations of aqueduct and water body, groove body and groove heading tape dynamic damping device 1 and spring 2, the relative motion that makes damper 1 and spring 2 produce relative aqueduct, control that this relative motion produces can further reduce the seismic response of aqueduct.In a word, aqueduct TLD, grid 4, damper 1, spring 2 play good mixing vibrations control action with 6 pairs of aqueducts of plumbous zinc neoprene bearing.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.
