Background technology
It is cheap since sliding and shock isolation materials are easy, it is made to be had a wide range of applications in civil engineering, and application is gone through History is remote.This kind of shock-dampening method can make superstructure generate approximate rigid body translation under larger earthquake effect, greatly reduce knot The rigidity of structure bottom, while structure can be by Frictional Slipping dissipation part energy, eventually by the isolation to earthquake and consumption It dissipates and achievees the purpose that reduce superstructure dynamic response.Sliding shock-damping can realize the independence in shock insulation and liquid sloshing period, Also there is preferable control action for liquid sloshing wave height while liquid storage structure dynamic response is reduced, make it in reservoir knot Advantage is shown in terms of structure damping, there is potential engineer application meaning.Although at present about Sliding-isolated Structures into A lot of research and application is gone, but still there is following deficiencies：
(1) although Sliding-isolated Structures can reduce the dynamic response of superstructure, its slippage is often also larger；
(2) traditional isolation structure and concrete spacing walls rigidity are all very big, once slippage, which transfinites, will generate collision, Structure can all have different degrees of damage with spacing walls in itself；
(3) in order to avoid the collision of Sliding-isolated Structures and spacing walls, in actual slip shock insulation engineering, mainly by pre- First horizontal displacement of the estimation Sliding-isolated Structures under geological process, resets the spacing size of structure and spacing walls, but by Limited and requirement in by place, spacing tend not to it is excessive, in addition the randomness of earthquake, under certain geological processes sliding every Shake structure is still within the bounds of possibility with what spacing walls collided, is badly in need of a kind of method for slowing down collision response.
Invention content
The object of the present invention is to provide a kind of, the sliding and shock isolation liquid storage structure of rubber block and spacing walls crusherbull zone side are set Method.
The present invention is to set the sliding and shock isolation liquid storage structure of rubber block and spacing walls crusherbull zone method, and step is：
(1) structure surrounding arrange spacing walls, according to structure requirement and earthquake of setting up defences determine Sliding-isolated Structures with The initial spacing of spacing walls can avoid sliding and shock isolation liquid storage structure under horizontal earthquake action damaging in slide surface generation Displacement；
(2) in spacing walls surface layout rubber block, the initial of Sliding-isolated Structures and spacing walls can be reduced by adding in rubber block Spacing, final Sliding-isolated Structures need the thickness for including initial spacing and both sides rubber block with spacing walls spacing, can subtract Small sliding and shock isolation liquid storage structure is contacted with spacing walls generates destructive impact force,
(3) it is asked with non-elastic collision unit simulation sliding and shock isolation liquid storage structure and the collision of damping rubber block in spacing walls Topic, with the buffering effect of the size reflection rubber block of impact force, the quantity and size of damping rubber block are controlled by impact force, sliding The impact force for moving spacing walls of the shock insulation liquid storage structure with setting damping rubber block can be calculated by following formula：

In formula：N is the number for colliding side damping rubber block, and α is rigidity amplification coefficient, value range caused by collision It is 2~2.5, A, KrIt is respectively the contact area, rigidity and thickness of padded coaming with d, n can use to consider nonlinear index It is 2.65.
In formula：COR is collision recovery coefficient；
(4) position for arranging rubber block is needed to carry out fixed point label in spacing walls, and spacing walls surface markers position into Row grinding process；
(5) rubber block is connected to the label of spacing walls using cementing material by quantity and dimensioned rubber block on demand Position.
The beneficial effects of the invention are as follows：The sliding and shock isolation liquid storage structure of rubber block and spacing walls crusherbull zone method are set, By its unique thinking, damping rubber block is added on concrete spacing walls surface, can be avoided straight between big rigidity object Connect collision；The setting of damping rubber block can greatly reduce instant shock power, then reduce the collision dynamic response of system；To touch The size for hitting power reflects the buffering effect of rubber block indirectly, and concept is concise.This sliding and shock isolation liquid storage structure and spacing walls Crusherbull zone method, materials are easy, durability is good, cheap, easy construction, contribute to engineer application, help to reduce ground The failure probability of the lower sliding and shock isolation liquid storage structure of shake effect.
