管幕施工引起的地面变形计算方法综述

Review of Methods Predicting Tunnel Excavation Induced Ground Subsidence

管幕施工会对管道周围的土体产生扰动,引起土体移动。分析了管幕施工的地面变形机理,对顶管施工引起的地面变形计算方法的发展概况及研究进展进行了综述,将地面变形计算方法归纳为经验法、理论法、数值法和实测数据分析法,提出了目前该领域研究中需要重点研究的课题和一些新的研究思路。

The ground subsidence as well as the disturbance of soil around the large diameter pipe excavation might be induced by the pipe jacking construction.This paper provides a review of the development of the methods that predicting the ground subsidence and a review of the ground subsidence mechanism.The ground subsidence methods can be categorized as：empirical,theoretical,numerical and statistical from observed data.Current research topics and their solutions are also discussed in the paper.
