摘要
分析了软土地层中顶管开挖引起的地面沉降及沉降槽形状预测方法．对沉降曲线的推导和分析显示，沉降曲线取决于顶管隧道轴线处上部的地面沉降和曲线的拐点到顶管轴线的水平距离．所推导的理论得到顶管工程实例的验证．
Ground settlement due to pipe jacking in soft soils is analyzed and a method is developed to predict the settlement curve. The analyses revealed that the settlement trough is determined by the settlement magnitude above the pipe axis and the level distance from the inflexion to the axis. The theories are verified by engineering cases.
