摘要
以上海虹桥综合交通枢纽地铁虹桥西站为背景,针对大空间地下工程钢筋混凝土支撑体系,提出按刚度均匀分布的支撑布置原则,以及大空间钢筋混凝土支撑体系等效线刚度的概念和计算法,计算分析考虑温度应力以及支撑立柱隆沉对支撑体系的影响,并通过现场监测对比分析验证理论分析与技术参数选取的合理性。
The article is base on the Raibow west metro of rainbow intergrated transport hub in Shanghai as background.To the large space＇s underground RC bracing system,it brings forward braces lay＇s principle according equality of stiffness＇ distributing,equivalent stiffness＇concept of the large space＇s RC bracing system and calculation method.It takes into accout the effection of temperature stress and resilience＇s repercussion to bracing system.It validates the rationality of theorial analysis and technical parameter＇s picking by contrasting and analyzing of monitoring on the spot.
