城市轨道交通建设中的地下车站深基坑工程,一般都有施工场地小、环境复杂、工期紧、社会影响大等特点。半逆作法因其能有效控制周边环境,加快施工工期而在轨道交通建设中发挥越来越重要的作用。通过工程实例,叙述了半逆作法的施工流程,施工中注意的要点及针对性措施,施工效果良好。
In the construction of urban rail transit, the deep foundation pit project of underground station generally has the characteristics of small construction site, complex environment, tight construction period and great social impact. Semi-inverse approach because of its ability to effectively control the surrounding environment, speed up the construction period and in the rail transit construction to play an increasingly important role. Through the engineering examples, the construction process of the semi-inverse method, the points to be noticed in the construction and the pertinent measures are described, and the construction effect is good.
