| 摘 要： | 对桩土共同作用理论做了探讨 ,论述了水浮力对桩与土的卸载及其对基础设计的影响 ;认为桩土应力比无法精确确定 ,桩土应力比应为一个范围值 ,在这范围地基及基础的安全均应得到保证 ;对目前复合桩基设计方法存在的问题进行了讨论 ,提出了改进的复合桩基与复合地基设计方法

| Abstract: | The theroy of soil-pile interaction and the effect of water buoyant force on the design methods of foundation are investigated in this paper.The stress ration of soil and pile can not be determined exactly,but should be positioned in some extent,in which the security of foundation should also be ensured.The present problems in design methods of composite pile foundation are discussed,and some advanced design methods of composite pile foundation and composite ground are put forward too. |

| Keywords: | Rigid composite pile foundation Composite ground Water buoyant force Bearing capacity Settlement |
