摘要
某深水防波堤工程水深18~30 m,软土层厚度超过30 m。为检验部分开挖换填抛石斜坡堤设计方案的地基稳定性和地基沉降,进行了防波堤软土地基离心模型试验。试验得到地基圆弧滑动抗力分项系数为1.19,与按规范验算的稳定性结果较一致;施工期地基沉降量约为总沉降量的50%,试验数值似偏小。试验验证了设计方案的可行性。
The water depth of a deepwater breakwater is 18~30 m,and the soft soil layer is more than 30 m.In order to test the foundation stability and foundation settlement of the design scheme for the excavation of the slope embankment,the experiment of the soft soil foundation centrifugal model was carried out.The experimental results show that the resistance partial factors of circuler sliding foundation is 1.19,which is consistent with the stability result according to the specification.The settlement amount of the foundation is about 50%of the total settlement amount,and the test value seems to be small.The experiment verifies the feasibility of the design scheme.
