| 摘 要： | 通过离心试验、数值模拟相结合的方法对抗突涌安全系数与某地铁车站基坑变形之间的关系进行了研究.研究结果表明,不应用单一的抗突涌安全系数控制不同开挖深度承压水基坑的降水程度,如要满足同样的基底隆起量要求,开挖深度越大,要求的抗突涌安全系数越大.

| Abstract: | This paper focused on the relationship between the safety coefficient of piping and foundation pit deformation.To research them,a centrifuge test and numerical analysis have been done.The results indicate that a uniform safety coefficient of piping can't be used to control dewatering with different depth of excavation.A bigger safety coefficient of piping is needed to meet the requirement of deformation when the foundation pit is deeper. |
