Research On The Structure Design And Analysis Of A Metro Transfer Station

This paper studies the island of a subway station as the main structure of a single arch, andsingle-column composite lining structure, considering the complicated conditions of theenvironment as a element. And it Using three-dimensional finite element analysis method oftheir analysis and design research, the main contents are as follows:(1) Summarize the current domestic and calculation methods for the design and analysisof the main structure of the shallow overburden underground stations, which focuses on thetwo-dimensional and three-dimensional finite element analysis of underground engineeringand its implementation steps;（2） According to the finite element analysis of underground engineering principles andrequirements, and the conditional environment and constructional environment. It establishedthe main structure with both adjacent building independent working together on the basis ofthree-dimensional finite element analysis model respectively. The use of finite elementsoftware Midas/GTS to calculate and analyze, which lead to the results of the mainstructure of the most unfavorable combination of load effects calculations.Other main control sections for the station and the main force member, were also establishedby finite element analysis model of the D bar system and three-dimensional compositestructures, and by force conditions under the action of the finite element analysis has beencorresponding calculations;(3)According to calculated results of load effects calculated in this article, and the designand checking of the bearing capacity and serviceability limit state design specifications inaccordance with the existing structure, the main structure of the underground stations of thisarticle, and related engineering practice to verify the correctness of the results of this paper.
