双线地铁盾构施工引起的地表沉降分析及施工控制研究

Ground Settlement Analysis and Construction Control Study Caused by Double-line Metro Shield Construction

最近几年以来,国家经济取得较快发展,由此推动城市现代化进程,现如今,地面交通已不满足人们出行的要求,由此国内很多城市更加注重对地下交通的研发。由于盾构法具有较高速度、较高精度,其与地面交通不冲突,进而被广泛应用于双线地铁施工中。本文对盾构隧道施工引起的地表沉降进行了分析,对地表动态变化情况进行了分析,对如何有效控制地表沉降进行了探讨,并提出了几点建议,希望能帮助到相关人士。

In recent years,the national economy has achieved rapid development,which has promoted the process of urban modernization.Nowadays,ground transportation no longer meets the requirements of people to travel,so many cities in China pay more attention to the research and development of underground transportation.Because of its high speed and high precision,the shield method does not conflict with ground traffic,and is widely used in the construction of double-track subways.This paper analyzes the surface settlement caused by shield tunnel construction and the dynamic changes of the surface,discusses how to effectively control the surface settlement,and puts forward some suggestions,hoping to help relevant people.
