摘　　要：运用随机介质法理论,研究开发出了隧道施工引起的地表移动及变形预测系统,实现了隧道开挖引起的地表沉降、倾斜、曲率、水平位移和水平变形预测,并对预测公式进行改进,预测了大断面分部开挖引起的地表移动及变形。工程实例分析表明该方法效果良好,具有一定的实用价值。Based on the theory of stochastic medium, a new tunnel movement and deformation prediction software code is developed. And it is used to predict the ground surface settlement, inclination, curvature, lateral movement and lateral deformation due to the tunnel excavation. And through modifying the formula, it can be applied to predicting the ground surface movement and deformation of large cross-section tunnel for staged construction. A case study shows that the prediction method developed can reach good results and has some practical value.
