Seismic finite element analysis of underground integrated pipe corridor based on generalized reaction displacement method

Abstract An underground integrated pipeline corridor is a long-line structure that accommodates various municipal pipelines such as water supply, reclaimed water, storm communication, heat, electricity, and natural gas. Seismic hazard the main factor affecting safety of this important urban lifeline project, so seismic analysis urgent. To end, in paper, based on generalized reaction displacement method, finite element model standard section pipe under action earthquake established, displacement, well internal force response earthquake, obtained. The results show junction between top outer slab key part for shear bending tests, reinforcement span also needs to be focused on. Simulation calculation by physical stochastic paper method more applicable suitable corridor, which lays foundation realizing refined dynamic reliability corridor.
