| 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。文中对顶管施工引起的地面变形机理、变形的原因等进行了分析 ,结合工程实例 ,对地面变形的规律进行了探讨 ,实例中地面最大隆起达到 12 8.2mm ,顶管施工引起的地面变形总体上是先隆起后沉降。

| Abstract: | Pipe jacking construction may disturb the soil around the pipes and cause soil movements. The mechanism and reason of ground deformation caused by pipe jacking construction are analysed. Combining with the case in study, the regularity of ground deformation is probed. In this case, the maximum ground upheaval is 128 2mm, and generally the ground upheaves at first and then subsides. |
