盾构下穿铁路路基及火车站站房地表沉降分析

Analysis on Ground Settlement of Shield Tunneling Under Railway Subgrade and Railway Station Building

现阶段,科学技术的发展十分迅速,并且城市化建设也加快了进程,所以,为了缓解交通压力,避免堵车等现象发生,城市交通线网的铺设范围就会逐渐扩大,并且下穿工程也开始慢慢增多。地铁盾构隧道在修建时,难免会造成各种邻近建(构)筑物的沉降以及变形,所以在进行地铁盾构隧道施工时,势必会影响运行以及使用。据此,针对盾构下穿铁路工程,必须要对下穿施工予以专项研究。

At present, the development of science and technology is very rapid, and the process of urbanization is also accelerated. Therefore,in order to alleviate the traffic pressure and avoid traffic jams, the laying scope of urban traffic network is gradually expanded, and the undercrossing projects are also gradually increasing. During the construction of subway shield tunnel, it is inevitable to cause the settlement and deformation of various adjacent buildings. Therefore, when the subway shield tunnel is constructed, it is bound to affect the operation and use.Therefore, it is necessary to study the construction of shield tunneling under railway.
