离心成型桩在软基中的承载效率

Load-carrying Efficiency of Centrifugal Shaping Concrete Square Pile in Soft Foundation

地基土的相对刚度条件变化时,不同几何截面形状桩的地基承载力效率存在一定的差异性,探讨了三种几何截面形式的离心成型桩,作为摩擦桩使用时地基承载力效率问题,指出在刚度比Eb/Es处于较小值时,采用离心方桩截面形式能获得更高的地基承载力效率。

There is the differences of the load-carrying efficiency among the plies with different sections according to changes of the relative stiffness of soil in the foundation. The load-carrying efficiency of the centrifugal shaping concrete square pile, com- posed of three different geometric cross sections, is discussed as the friction pile. It is found that the load-carrying efficiency of it is higher under the condition that the stiffness ratio Eb/Es is small.
