摘　　要：顶管施工会对周围土体产生扰动,引起土体移动。而相对于圆形顶管,矩形顶管对周围土体的扰动更大,从而引起的地表变形也更大。文章结合工程实例,对矩形顶管施工引起的地表变形规律进行了探讨,分析矩形顶管施工引起土体移动的影响因素,为同类工程的设计与施工提供参考。Pipe jacking construction may disturb the soil around the pipes and cause soil movements.Relative to circular pipe jacking, rectangular pipe jacking construction may disturb the soil more heavily and cause more surface deformation.Combi - ning with the case in study,the regularity of surface deformation caused by rectangular Pipe Jacking Construction is probed,the reasons of soil movement caused by rectangular Pipe Jacking Construction are analyzed.The conclusion should be valuable as reference for the similar engineering to design and construct in the future.
