摘要
顶管施工会对管道周围的土体产生扰动,引起土体移动。分析了顶管施工引起的地面变形机理,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,把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。
Pipe jacking construction may induce disturbance of soil around the pipe and result in ground movements. The mechanisms to produce surface deformation was discussed. The development and research progress of ground deformation induced by pipe jacking construction was reviewed. Ground deformation can be calculated with empirical methods, theoretic or numerical method, also by basing on the measured data. Some new ideas and problems that should be investigated particularly was also proposed.
