摘　　要：采用非文克尔地基模型,依据Mindlin的弹性理论解,建立地基的柔度矩阵,将桩视为由侧向弹簧支承的连续梁,弹簧的刚度为变刚度,采用逐次迭代的方法求解,并与实测结果对比,其吻合程度较好。In this paper,non-Winkler foundation model is adopted. On the basis of Mindlin's solution of e-lastic theory,the compliance matrix of foundation is established. The pile is regarded as a continous beam laterally supported by springs. The step-by-step iteration is used in solution, and the results have a good a-greement with the measured data.
