Structural Optimization and Sensitivity Analysis of Column-Free Large-Span Subway Station
In view of the mechanical behavior of column-free large-span subway station structures,different structural models of roof and floor as well as factors such as span,cover soil,and lateral pressure coefficient that affect the mechanical behavior of underground station structures are selected as the research objects.The Midas GTS numerical simulation software is used to establish models for calculation and analysis,and optimal structural types for column-free large-span subway stations are obtained.The research results show that the installation of arched roof and floor in column-free structures has a significant effect on improving the mechanical behav-ior of the structure,and factors such as span,cover soil,and lateral pressure coefficient have different sensi-tivity effects on the mechanical behavior of column-free structures.
