ELASTO-PLASTIC AND STOCHASTIC MEDIUM METHOD AND APPLICATION IN ANALYSIS OF GROUND DISPLACEMENT AND STRESS CHANGE DUE TO TUNNEL CONSTRUCTION
弹塑性随机介质法及其在隧道施工引起的岩层位移及应力分析中的应用

In the application of stochastic medium theory, it is assumed that ground movement process is of the property of stochastic process, and the ground movement and deformation due to tunnel excavation can be calculated. In the application of elasto-plastic medium theory, the rock and soil are assumed to be elasto-plastic medium, and the stress change due to tunnel excavation can be calculated, too. The comparison between the field measurements and the calculated results shows the validity of the proposed method.
