摘　　要：运用随机介质法理论,研究开发出城市隧道开挖引起的地表沉降及变形预测系统,并对预测公式进行改进,实现十字隔墙法施工隧道分部开挖引起的地表沉降、倾斜、曲率、水平位移和水平变形预测。对中国第一条海底隧道十字隔墙法施工引起的地表沉降及变形进行预测,通过实测值与预测值比较,说明该方法效果良好,具有一定的实用价值。Based on the theory of stochastic medium theory,a new urban tunnel movement and deformation prediction programme is developed,and the formula is modified.It is reliable to predict the ground settlement,inclination,curvature,lateral movement and lateral deformation due to tunnel excavation with cross diaphragm（CRD） method.A case that has been applied to prediction of the ground settlement and deformation of the first subsea tunnel constructed with large cross-section in China shows that the prediction method is effective;and it can provide valuable references to practical engineering.
