【摘要】 把匀质地基中的桩、土之间力传递问题当作两种不同介质相互接触的平面应变问题来研究．用边界无法来描述桩、土之间力传递的全过程，并根据桩静载荷试验的Ｐ－Ｓ曲线，反分析地基土体力学参数（压缩模量Ｅｓ和泊松比μ），反分析采用单纯形法．计算表明，这能较好地反映实际工程中桩的工作情况．更多还原

【Abstract】 The force transmission between pile and soil in homogeneous base is studied as plane strain occurred by mutual contact of two different media.The whole process of force transmission between pile and soil is described by boudary element method.An inverse analysis is conducted on the parameters of soil mechanics of the base,compressed modulus Es and Poisson’s ration,according to P￣S curve of Pile dead load test.The inverse analysis is conducted by adopting simplex method. As demonstrated by the calculation, the working condition of pile in practical engineering can be well reflected.更多还原
