一直以来,地铁盾构施工拥有安全、智能、快捷、地层实用性广等特点。在国内的地铁工程项目建设中,盾构施工法得到广泛的应用。但是采用盾构法修建城市地铁隧道时,如何预测和控制因幵挖造成的地表沉降和邻近建筑物沉降,避免对城市建筑物的损害,现已成为施工所面临的一个重要问题。本文结合工程实例,在数值模拟数据计算的基础上研究新建盾构隧道侧穿建筑物基础产生的地面沉降。
All along, the subway shield construction has a safe, intelligent, fast, widely applicable strata and other characteristics. In the construction of subway project in China, shield construction method has been widely used. However, how to predict and control the surface subsidence caused by digging and the settlement of adjacent buildings to avoid the damage to the urban buildings when using the shield method to construct urban subway tunnels has now become an important issue in construction. Based on the numerical calculation of numerical simulation, this paper studies the ground subsidence caused by the side-by-side building foundation of a new shield tunnel.
