挤压式盾构隧道施工引起的地表移动及变形

Ground Surface Movement and Deformation Due to Tunnel Construction by Squeezing Shield

视挤压式盾构施工隧道引起的地表移动为一随机过程，应用随机介质理论对所引起的地表移动和变形进行了分析。工程实例分析表明，该分析方法效果良好。

The ground surface heave due to tunnel construction by squeeing shield is considered as a stochastic process and the stochastic medium theory is applied to the prediction of the ground surface movement and deformation. An example of case history shows that the prediction method developed in this paper can reach good results.
