地铁站房建设工程中钢拱梁结构优化研究

RESEARCH ON OPTIMIZATION OF STEEL ARCH BEAM STRUCTURE IN SUBWAY STATION BUILDING CONSTRUCTION

地铁建设工程中,站房屋面施工中钢拱梁节点形式是影响节点受力的主要因素之一。基于此,以浙江省金华市东阳市横店镇的轨道交通站房建设实例为基础,对站房屋面施工中钢拱梁节点的优化方案展开研究,从节点连接的承载能力和节点的转动能力两方面进行钢拱梁节点优化研究。

In the subway construction project,the steel arch beam joint form is one of the main factors that affect the joint force in the construction of the station floor.Based on this,the paper studies the optimization scheme of steel arch beam joints in the construction of station building surface based on the example of rail transit station building construction in Hengdian Town,Dongyang City,Jinhua City,Zhejiang Province.It explains the optimization control content of steel arch beam members from two aspects of steel arch beam member fabrication and steel arch beam member welding,and carries out the optimization research of steel arch beam joints from two aspects of joint connection bearing capacity and joint rotation capacity.
