摘要
基于考虑围护结构刚度折减的链杆模型,对某软弱地层中的标准二层地铁车站复合墙结构进行了计算分析,得到复合墙结构的受力特性,并重点分析了覆土厚度、地基加固、围护结构刚度对复合墙结构受力的影响,提出了简化链杆模型。
Based on envelope stiffness-reduced chain-pole model,this paper introduces the computational analysis on compound-wall structure of one 2-floor subway station in the thick soft soil foundation,the behavior characteristics of compound-wall structure is obtained. The thickness of covering soil,the foundation reinforcement as well as the envelope stiffness are especially analyzed to counter the simplified chain-pole model.
