The invention relates to an underground structure anti-seismic toughness structure system, and belongs to the technical field of structure seismic resistance. The system is used for reducing reactionand residual deformation of an underground structure in an earthquake, realizes quick recovery of a structure function after the earthquake through self-resetting force of dampers, and comprises enclosure structures, the underground structure, embedded parts and the dampers, wherein the enclosure structures are symmetrically distributed on the two sides of the structure, fertilizer grooves are formed between the enclosure structures and the underground structure, an underground structure bottom plate and the enclosure structures are poured together, the embedded parts are arranged on the enclosure structures and side walls of the underground structure, the displacement type dampers are connected between the enclosure structures and the side walls of the underground structure through the embedded parts, the dampers are horizontally arranged, and the damping distance and parameters depend on the horizontal rigidity of a surrounding rock-soil body and the maximum allowable deformation ofthe underground structure and the surrounding rock-soil body. The underground structure anti-seismic toughness system is a toughness anti-seismic structure system which gives consideration to both underground structure anti-seismic capacity and post-seismic function rapid recovery.
Description
technical field [0001] The invention relates to an underground structure anti-seismic toughness structure system, which belongs to the technical field of anti-seismic structures. Background technique [0002] At present, my country is undergoing large-scale urban space development and construction, and the construction of urban underground structures represented by subways has made rapid progress. Historical earthquake damage shows that during the earthquake, the gravity and vertical inertial force of the overlying soil of the underground structure cause a significant increase in the axial compression ratio of the structure's central column and a decrease in the lateral deformation capacity. damage, leading to the collapse of the entire structure. The underground structure exists in the soil, and its seismic response is constrained by the deformation of the surrounding rock and soil. Therefore, the key to reducing the seismic response of the structure is to reduce the horiz...
