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。
Through the combination of centrifugal test and numerical simulation, the relationship between the inrush safety coefficient and the deformation of foundation pit in a metro station was studied. The results show that a single surge safety factor should not be used to control the degree of precipitation in water-bearing pits under different excavation depths. To meet the same requirement for base bump, the greater the excavation depth, the required surge safety factor The bigger
