层状粘土地基上柔性条形基础的 Biot 固结沉降分析

Analysis of Biot's Consolidation Settlement of Flexible Strip Foundation on Layered Clay

采用层状粘土地基模型模拟实际地基的土层参数随深度按层状变化的情况，采用Ｌａｐｌａｃｅ－Ｆｏｕｒｉｅｒ联合变换和传播矩阵技术，由Ｂｉｏｔ固结方程导出了层状粘土地基固结变形的位移，应力及其柔性条形基础沉降的解极表达式．给出的公式简洁明了，计算精度高，计算量小．文末给出了实例计算的数值结果．

The layered clay model is used to imitate actual change of foundation soil parameters by layers along the depth. The analytical solutions of displacements and stresses of layered clay foundation and settlement of flexible foundation are derived from Biot's consolidation equations using Laplace-Fourier mixed transforms and transfer matrix method. The formulas given are simlpe and clear, small in amount of computation and high numerical precision. The numerical results of an examlpe are given in the end of the paper.
