Abstract
The utility model provides an underground structure high damping subtracting shock insulation structure, including ground even wall and underground structure, underground structure be the rectangle, ground even is equipped with the shock attenuation wall between wall and the underground structure, the shock attenuation wall is not the mat surface with the ground even contact surface of wall, ground even wall passes through the mutual interlock of mat surface with the shock attenuation wall. The utility model discloses can control the soil body and impose on underground structure's displacement, also can reduce the ground vibration energy who transferes underground structure to reach and avoid or reduce the destruction of underground structure in the earthquake.
Description
Technical field
The utility model relates to the seismic isolation and reduction structure of underground structure, is specially a kind of underground structure high-damping isolation structure.
Background technology
Because the anti-seismic problem research history of underground structure is shorter, the case that violent earthquake simultaneously causes underground structure to destroy is limited, thus subtracts the research wretched insufficiency of isolation measure for underground structure.In addition, underground construction belongs to concealed work, subtracts the enforcement of isolation measure also by the restriction of many execution conditions, environment.At present, what underground structure was the most frequently used subtracts isolation measure is arrange buffer layer in underground structure periphery.The method derives from mining tunnel, has certain flexible special material layer by one deck, reaches the object consuming earthquake motion energy.The method is feasible in theory, but in Practical Project, application is limited to buffer layer characteristic, as durability, impermeability, compressibilty etc.
Also buffer layer method is being applied on Urban Underground rail traffic structure at present, but there is the problem of following several aspect in the method: 1) subway tunnel generally adopts shield construction at present, work progress, entirely in shield machine built-in function, applies peripheral buffer layer comparatively difficult; Even if subway station generally adopts cut and cover tunneling, but buffer layer needs to expand excavation area; 2) because buffer layer generally has certain elasticity, under the long-term vibrating load effect of train, certain compressive strain can be there is in buffer layer, for the shield tunnel of Deep Thick Soft Ground Area, this obviously can aggravate the sedimentation of ground, thus causing the uneven compliance of track, the problems such as the wheel-rail wear and tear that initiation is relevant, vibration and quadratic noise are excessive, these all limit the application of buffer layer on urban track traffic Seismic Isolation And Dissipation of Civil Structures.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of underground structure high-damping isolation structure, the displacement that the soil body imposes on underground structure can be controlled, also can reduce the earthquake motion energy passing to underground structure, thus reach from or reduce the destruction of underground structure in earthquake.
The utility model for solving the problems of the technologies described above taked technical scheme is: a kind of underground structure high-damping isolation structure, comprise ground-connecting-wall and underground structure, it is characterized in that: described underground structure is rectangle, high damping shock absorption wall is provided with between ground-connecting-wall and underground structure, the contact surface of shock absorption wall and ground-connecting-wall is matsurface, and ground-connecting-wall is engaged by matsurface mutually with shock absorption wall.
By such scheme, described shock absorption wall is provided with waterproofing course near the surface of underground structure.
By such scheme, the matsurface of described shock absorption wall is provided with hole and projection, and the matsurface of described ground-connecting-wall is provided with projection and the hole of hole and protrusions on the matsurface with shock absorption wall.
The beneficial effects of the utility model are: by increase by one with the shock absorption wall of ground-connecting-wall Rough Contact, utilize high damping shock absorption wall can effectively absorb seismic wave energy, highly seismic region or the Underground Rectangular structure higher to shockproof requirements can be met; Utilize the friction energy between ground-connecting-wall and shock absorption wall to consume the seismic wave energy of a part simultaneously; And consider structure construction actual conditions, structure is simple, easy construction; Be not arranged on the bottom of structure, extra sedimentation can not be produced as buffer layer, thus the uneven compliance of operation phase track can not be aggravated; The utility model structure effectively can improve the shock resistance of 1-2 grade of rectangle underground structure.

Fig. 1 is the structural representation of the utility model one embodiment.
In figure: 1-ground-connecting-wall, 2-shock absorption wall, 3-waterproofing course, 4-underground structure.
Detailed description of the invention
Fig. 1 is the structural representation of the utility model one embodiment, comprise ground-connecting-wall 1 and underground structure 4, described underground structure 4 is rectangle, shock absorption wall 2 is provided with between ground-connecting-wall 1 and underground structure 4, shock absorption wall 2 is matsurface with the contact surface of ground-connecting-wall 1, and ground-connecting-wall 1 is engaged by matsurface mutually with shock absorption wall 2.Matsurface herein refers to the matsurface that in field of civil engineering, those of ordinary skill is understood, can be that conventional method is constructed the concrete surface obtained, also can in order to reach better effect, the artificial projection some holes being set on the contact surface He matching, what the utility model mainly utilized is the friction effect consumed energy that two matsurfaces produce, and is not particularly limited specifically coarse degree.
Preferably, shock absorption wall 2 is provided with waterproofing course 3 near the surface of underground structure 4.
Preferably, the matsurface of described shock absorption wall 2 is provided with hole and projection, and the matsurface of described ground-connecting-wall 1 is provided with projection and the hole of hole and protrusions on the matsurface with shock absorption wall.
In the present embodiment, during Specific construction:
1) first apply ground-connecting-wall 1 routinely as space enclosing structure, but now should note need polishing on ground-connecting-wall when designing, people for making ground-connecting-wall 1 rough surface, to reach better damping effect;
2) after ground-connecting-wall concrete reaches design strength, prepare by designing requirement and build shock absorption wall 2, now also should note also polishing in the face that contacts with ground-connecting-wall 1 at shock absorption wall 2, make the roughness that the surface of shock absorption wall 2 also reaches certain;
3) after shock absorption wall intensity reaches designing requirement, outside shock absorption wall, one deck waterproofing course 3 is laid;
4) underground structure 4 is applied.
Above embodiment is only for illustration of design philosophy of the present utility model and feature, and its object is to enable those skilled in the art understand content of the present utility model and implement according to this, protection domain of the present utility model is not limited to above-described embodiment.So the equivalent variations that the principle that all foundation the utility model disclose, mentality of designing are done or modification, all within protection domain of the present utility model.
