摘　　要：在二维有限元分析方法中考虑了固结比Ｋｃ变化对孔压发展的影响，编制了专用程序，可研究有建筑物存在时的地基液化问题，计算结果与模型试验结果比较符合，说明该方法可应用于实际工程分析．The edects of change of consolidation ratio K. on development of pore water pressurein 2-D FEM analySis are studied. Relative special program which can be used toliquefaction problems of foundation in the case of exsisting of building is presented. Thecomparison between the resultS from calculation and model test shows that the method proposedin the paper is applicable to analySis -of practical engineering.
