摘要
根据Biot固结理论,采用有限单元法对简化为二维问题的碎石桩加固地基进行计算。在单元划分时,碎石桩作为竖向土层处理。根据计算结果,本文对碎石桩复合地基的应力分布、孔隙水压力、固结度以及变形等问题进行了分析。
Based on Biot's consolidation theory, computations by FEM are made on the simplified two-dimensional problem of an improved ground with stone columns, which are treated as vertical soil strata in the element division. Stress distribution, excess pore water pressure, degree of consolidation and deformation, etc. of this composite ground are computed and analyzed.
