Abstract

The invention discloses an anti-earthquake analysis method for a metro station in a water-rich stratum, and solves the anti-earthquake analysis problem of the metro station in the water-rich stratum. By use of the method, under an earthquake function, a mutual function between the metro station and a surrounding soil layer as well as underground water in the water-rich stratum under the earthquake function can be analyzed so as to provide a design and construction basis for metro station construction. The anti-earthquake analysis method has the technical scheme that the method comprises the following steps that: according to a soil-structure earthquake mutual function model and a Biots seepage consolidation model, determining the anti-earthquake analysis model of the metro station in the water-rich stratum, and determining the mechanical parameter of a water-soil-structure coupling function model; setting position arrangement monitoring points in the water-soil-structure coupling function model; determining an earthquake acceleration time history wave; and carrying out anti-earthquake analysis on the water-soil-structure coupling function model.

Description

technical field [0001] The invention relates to the technical field of anti-seismic analysis of subway stations, in particular to an anti-seismic analysis method for subway stations in water-rich strata. Background technique [0002] With the acceleration of urbanization, urban traffic conditions and environmental conditions are deteriorating day by day, and the development of a large-capacity rapid public transport system with subways as the backbone is an important way to solve the problem. It is generally believed that subway stations are constrained by the surrounding soil and have better seismic performance. However, the existing earthquake damage shows that the existing subway stations are not safe. For example, the 7.2-magnitude Hanshin earthquake in Japan in 1995 caused serious damage to the subway stations in Kobe. Once the subway station is damaged by an earthquake, it will bring great difficulties to the earthquake emergency response and post-earthquake repair wo...
