在地铁车站施工过程当中,施工技术难免会造成周围土体的扰动,地面发生一定的沉降现象或者是围护结构侧移等各种不良状况。这些现象主要是由于地铁车站周围环境和地质条件的特殊性所导致的,想要有效解决这些问题就必须要用深基坑支护施工方法,其可以更好地确保整个地铁车站施工过程的安全稳定进行。鉴于此,本文先对地铁车站深基坑施工特点进行了一定的分析,然后阐述了各种地铁车站深基坑支护施工方法。
During the subway station construction process, the construction technology will inevitably cause the disturbance of the surrounding soil, the surface subsidence phenomenon occurs or the building envelope lateral displacement and other adverse conditions. These phenomena are mainly caused by the particularity of the surrounding environment and geological conditions of the subway station. To effectively solve these problems, it is necessary to use the deep foundation pit support construction method, which can better ensure the safety of the entire metro station construction process Stable. In view of this, this paper first analyzes the construction characteristics of deep foundation pit of subway station, and then expounds the construction method of deep foundation pit support for various metro stations.
