| 摘 要： | 结合连霍高速公路某段道路扩宽工程,设计了柔性基础条件下的四桩复合地基进行现场静荷载试验.试验证明柔性基础下刚性桩复合地基的承载力低于刚性基础下复合地基且沉降变形较大,二者破坏模式完全不同.桩土应力比在加荷初期较大,柔性基础下复合地基的设计应按变形控制.

| Abstract: | Combining with Lian-Huo highway expanding project,on-site static test of four piles composite foundation is designed under soft foundation.It proves that bearing capacity and settlement of rigid piles under soft soil foundation are larger than that of composite foundation under rigid foundation,and their failure modes are different completely.Secondly,stress ratio between piles and soil is large at initial stage.Thirdly,design of composite foundation under soft foundation should be controlled according to deformation. |

| Keywords: | composite foundation bearing capacity stress ratio between pile and soil test research |
