随着城市化进程的加快,城市人口的数量正在不断增多,这对城市的交通带来了非常大的挑战。为了有效缓解城市交通压力,建造地铁工程成为了一个非常不错的选择。但是,地铁工程是一项工程量大、技术要求高的工程。在地下作业时存在着很多的问题。当前,比较常用的施工方法是深层地铁盾构施工法,然而该种方法会对地铁施工周围的土体造成一定的扰动,进而造成土体出现水平位移的情况以及地层沉降的情况出现。特别是土体水平位移问题更是当前地铁建造中的重要问题,如何解决这一问题,保证施工质量成为了十分关键的因素。
With the acceleration of urbanization, the number of urban population is constantly increasing, which poses a very big challenge to urban traffic. In order to effectively ease the pressure of urban traffic, the construction of subway projects has become a very good choice. However, the MTR project is a project with large quantities and high technical requirements. There are many problems when working underground. At present, the most commonly used construction method is the deep subway shield construction method, however, this method will cause some disturbance to the soil around the subway construction, resulting in the occurrence of horizontal displacement of the soil mass and formation subsidence. In particular, the issue of horizontal displacement of soil is an important issue in the current subway construction. How to solve this problem and ensure the construction quality has become a very crucial factor.
