摘要

从振冲碎石桩的变形、受力机制出发，提出相应的假设条件，利用弹性力学和Biot固结理论建立了可以考虑固结问题的振冲碎石桩复合的平面有限元分析弹性复合模型，并编制相应的有限元分析程序APOSE。通过算例考证了APOSE的可靠性和有效性，APOSE程序可以用于分析研究振冲碎石桩地基、砂井地基等类似复合地基沉降变形和固结问题。

Abstract

Based on studying the mechanism of deformation and bearing capacity of vibro-replacement stone column foundation

the assumptive conditions are presented. The composite two-dimensional numerical model of stone columns is estabilished; this model considers the couple of stress-strain with Biot consolidation and the reinforced efficiency

the finite element analysis program (analysis program of soil engineering) is developed according to this model. The reliability and validity of APOSE is verified by two simple examples. APOSE can be applied to analyze the consolidation and subsidence of vibro-replacement stone columns and sand well compound foundation

etc..
