摘要
根据沉桩时桩周土体的受力及变位特性 ,文章运用了极值原理分别从静力学和考虑速度场两方面出发 ,推导并给出了桩挤土效应的计算公式。同时结合工程实例进行了计算和分析 ,与试验结果进行了比较 。
According to the stress and strain condition of the soil around a pile,two formulas are developed based the extremum principle, with which the radius of plasticity area can be determined. In addition, a case history is calculated by the formulas and the result is analyzed.And the result is proved to be satisfactory for engineering application.
