Description
Technical Field
The invention belongs to the technical field of shock absorption of civil engineering structures, and particularly relates to a shock absorption treatment method for a subway station structure.
Background
For a long time, researchers and practitioners consider that the underground structure is buried in the soil, the underground structure moves and deforms along with the soil body under the action of the earthquake, the influence of the earthquake on the underground structure is small, the field of earthquake resistance of the underground structure is not concerned too much, and only the gravity center is placed on the earthquake resistance analysis and design of the ground structure. However, seismic damage over the last three decades has shown that subsurface structures are not as perceived as before under seismic action. On 1 month 17 1995, japan suffered from the sakashen earthquake of level 7.2 in the city of the magical household, and the water supply and drainage lines of several cities in the sakashen area suffered from a great degree of damage, even much lost the function of use. In 2008, strong earthquake of level 8.0 occurs in Wenchen in China, local damage occurs in the main body structure of 4 stations in the city, dense cracks are generated in a Loongxi tunnel 2km away from the middle earthquake, reinforcing steel bars are exposed or even sheared off, and tunnel inverted arches are damaged.
Joints of different utility are often provided in buildings. Such as deformation joints, construction joints, etc. The deformation joints are reserved structural joints for preventing the deformation of the building under the action of external factors, so that the reserved structural joints are cracked and damaged. The deformation joint can be divided into an expansion joint, a sedimentation joint and a shockproof joint. The width of the deformation joint of most of the basement is not more than 60mm, and the deformation joint is in the form of a straight joint with equal width.
In the tunnel, the connection part of the connecting channel and the main tunnel is a part with extremely complex stress and deformation. The stress and deformation in the coordination structure system of the deformation joint are arranged at the connecting part of the connecting channel and the main tunnel, which belongs to common technical means. At present, the deformation joint arrangement of the part still adopts the construction mode of the expansion joint and the settlement joint of the traditional civil building. The shape is mainly in the forms of flat joints, staggered joint joints, concave-convex joints and the like; the caulking and covering treatment is needed; the seam is filled with elastic waterproof materials such as asphalt hemp thread, ointment, rubber strip, foam plastic and the like. When the gap is wider, the gap is covered by galvanized iron sheet, color steel sheet, aluminum sheet and other metal regulating sheets.
The traditional deformation joint cannot adapt to the special requirements of uneven settlement and earthquake resistance of complex connection of a connecting channel and a main tunnel, and has the following defects:
(1) The metal regulating sheets at two sides of the conventional connecting channel deformation joint can only limit the excessive difference deformation of the connecting channel and the vertical direction of the main tunnel, but have no limiting effect on the dislocation in other directions, and the difference deformation at the interface is often multidirectional.
(2) When the deformation of the traditional connecting channel deformation joint reaches a set value, the metal adjusting piece is locked, cannot be automatically adjusted and has no self-adaptive capacity.
(3) The traditional connecting channel deformation joint is not specially designed for earthquake resistance.
