摘要
以西安地铁5号线长鸣路站为工程背景,对湿陷性黄土的工程特性、湿陷机理、发生湿陷的必要条件进行介绍.分析地铁工程与民建工程地基的受力特点及二者的差异性,对地铁工程的浸水来源、浸水可能性进行阐述.参照《湿陷性黄土地区建筑规范》,根据地铁工程基底的受力特征,提出地铁工程穿越湿陷性黄土层的处理原则.依据制定的原则对长呜路站湿陷性黄土地基处理进行判断分析,为类似工程的设计提供参考.
Taking Changnaing Road Station of Xi’an Metro Line 5 as an example,this paper introduced the engineering characteristics of collapsible loess,the mechanism of collapsibility,and the necessary conditions for collapse.Referring to the Code for building construction in collapsible loess regions,this paper analyzed the stress characteristics of the foundation of metro engineering and civil engineering as well as the differences between them,studied the stress characteristics of the foundation of metro engineering,and put forward the treatment principles of metro engineering passing through the collapsible loess layer,judgment and analysis were carried out for the treatment of the collapsible loess foundation in Changming Road Station in basis of the principle,which could provide certain reference for the design of similar projects.
