摘 要: | 通过波流水槽试验以及水平载荷试验,对砂性-黏性土中的4种不同工况下沉井加桩基础的局部冲刷前后承载力变化情况进行了研究。在4组不同工况试验中,沉井埋深均设置为1 cm,上覆黏性土层厚度设置为1,5,10 cm。试验结果表明:上覆黏性土为1 cm的情况下,冲刷前后水平承载力衰减较上覆黏性土5,10 cm前后承载力衰减明显增加。

Experimental Study on the Souring Effect to the Horizontal Bearing Capacity of the Caisson-pile Composite Foundation in Clay-sand Soil Stratum |
| |
Abstract: | Wave flume experiment and horizontal loading test are carried out in four engineering conditions to explore the change of the bearing capacity of the caisson-pile composite foundation undergoing the scouring. In the four conditions, the caisson buried depth is set to 1 cm and the overlying clay soil layer thickness is set to 1,5,10 cm. The results show that the horizontal bearing capacity attenuation of the foundation after the souring in the 1 cm condition is significantly larger than the overlying day soil of 5 cm condition and 10 cm condition. |
