地铁车站侧墙施工模板选型与设计验算

Model selection and design calculation for side wall construction of subway station

随着城市人口不断增加,城市地面交通压力逐渐困扰城市发展,因此许多大中型城市陆续开始地铁建设。无论选用明挖法还是暗挖法,车站模板的施工质量决定工程质量,尤其是侧墙模板的施工。结合以青岛地区某地铁车站侧墙模板施工实例,从施工性及经济性对大钢模板与传统模板的选型进行比选,并用SAP2000有限元软件对侧墙体系进行验算。

Nowadays with the growing urban population, the city ground traffic pressure has bothered the urban development, and the subway constructionhas started in many large and medium-sized cities. The construction quality of open cut or underground excavation of subway station model decides the engineering quality, especially the lateral wall of the template construction is more important. In combination with the construction of a subway station side wall template in Qingdao area, the large steel formwork and the traditional template were compared and selected in terms of construction and economy, and SAP2000 finite element software was used for calculating the lateral wall system.
