盾构法施工引起的地面沉降浅析

文中针对盾构施工过程中的地面沉降进行了浅析,主要分析目标为苏州地铁2号线迎尹区间国香雅苑小区,文中对盾构法施工造成地表沉降的发展过程进行了简要分析。对地铁采用盾构法施工的铁区间隧道引起地表沉降的原因、过程及规律进行了较为详细的分析,并结合地铁隧道盾构法施工工程实例,利用线性回归计算理论拟合观测点的线性方程,来预测地表沉降和指导安全高效的施工。最后将分析数据与工程实际监测测量数据进行对比,得出相应的结果并提出防止地表沉降的控制措施,以期为类似工程施工提供有益的参考和帮助。

Analysis on Ground Subsidence Caused by Shield Construction Process

This article analyzed the shield construction process of ground subsidence,the main analysis of the target for Suzhou Metro Line 2 Ying Yin interval of guoxiangyayuan neighbour hood. this paper briefly analyzes the development process of groundsettlement caused by shield construction. The full text of the subway tunnel shield construction caused ground settlement,and rules are analyzed in detail,and combined with the shield tunnel construction project,by using the linear regression calculation of linear equation fitting observation points,to forecast the round settlement in construction and guide the safe and efficient. The analysis of data and actual measurement data are compared,the corresponding results and put forward measures to control ground settlement,so as to provide reference and help for the construction of similar projects.
