| 摘 要： | 应用有限棱柱单元法对群桩与土相互作用系统进行了三维弹塑性分析，并以无限棱柱元模拟半无限空间地基土的边界条件。在计算中以理想弹塑性弹簧模拟桩土之间的相互作用，地基土的本构模型采用修正剑桥模型。主要分析了在集中荷载下由４根长桩组成的群桩与土相互作用系统，通过具有不同径距比的群桩系统的计算，得到一组承台中心的荷载－沉降曲线。

| Abstract: | In this paper, the three dimensional elasto plastic analysis of a group pile soil interaction system is made by using the finite prism element method. The semi infiite domain boundary conditions are simulated by the infinite prism element. The interaction between pile and soil is simulated by ideal elaso plastic shearing springs. The revised Cambridge yield model is adopted for the soil. An interaction system of soil and group pile consisting of four long piles under the action of a concentrated load is analyzed as an example. Through the calculation of various spacing diameter ratios, a set of load settlement curves are obtained. |
