| 摘 要： | 为了选择富水地层地铁隧道开挖的最佳施工方法，考虑流固耦合、时间和施工3种效应的综合作用，对在富水软土地层中开挖地铁隧道引起的地表沉降进行了离心模型试验，并对降水、动态降水和非降水3种施工方法进行了对比研究．结果表明，非降水施工是控制地表沉降最有效的方法．研究成果已成功地应用于深圳地铁工程中．

| Abstract: | To choose the optimum construction method for metro tunneling in saturated soft clay strata, the control effects of pumping, dynamic pumping and un-pumping construction methods on ground surface subsidence caused by metro tunneling in saturated soft clay strata were compared through centrifugal model tests by taking the integrated effects of fluid-solid coupling, time and tunneling process into account. The research result shows that the un-pumping construction method is the most effective method for metro tunneling in saturated soft clay Strata in the three methods. The research results have been successfully applied in the construction of the Shenzhen metro. |
