The Application of Response Displacement Method in Seismic Analysis of Cross Section of Underground Structure
The response displacement method is a seismic response analysis method that inputs one-dimensional soil mechanical parameters.Based on the calculation example of an underground subway station project in Guangzhou,this paper briefly introduces the theoretical basis and calculation process of the response displacement method.According to relevant specifications and calculation methods provided in the paper,the strain analysis model of plane frame is established by software,and the analysis results of earthquake action and quasi-permanent combination are compared.The analysis results show that the earthquake action does not play a controlling role in the internal force calculation of the conventional rectangular section subway station.
