Intelligent truss temporary reinforcement system for zero-distance underpass of existing subway station

Abstract

The present application belongs to the technical field of subway station construction, and provides an intelligent truss temporary reinforcement system for zero-distance underpass of existing subway station, comprising: a compensation influence range identification module: through historical displacement monitoring data, combined with the stiffness matrix model of the existing station structure and the stratum parameters, the associated nodes influenced by the jacking compensation of the to-be-compensated point are identified through numerical simulation, and a compensation influence mapping relationship is generated. Based on numerical simulation, the range of associated nodes influenced by the jacking compensation of any to-be-compensated point is identified in advance, and a quantitative compensation influence mapping relationship is generated. In the multi-point collaborative synchronous compensation module, the mapping relationship is used to screen the main control jack and its associated collaborative jacks, forming a to-be-compensated jack combination, ensuring that the compensation operation covers all possible affected areas, reducing the chain deformation effect caused by local jacking, and realizing precise collaborative control of the station floor.
