摘　　要：Geddes应力解最初是为了求解匀质地基中刚性单桩应力分布而提出的,而现实中土层常常是成层的,桩也是可压缩的(尤其是超长桩和复合地基中的桩体),因此,用Geddes解计算沉降具有与生俱来的模型误差。本文分析了Geddes应力解求解沉降的模型误差,指出位移协调法不能确定侧阻分布。Geddes stress solution was firstly presented intended to solve the stress distribution in isotropic soil caused by a rigid isolated pile. However, in reality the soil is often layered and the pile is often compressible, and thus there exist modal error when calculating settlement with Geddes soultion. In this article, the modal error is analyzed, and further study shows that complicated compatibility method widely used is unable to give the stress distribution of single pile.
