摘　　要：本文以桩—土相互作用的关系为基本点,对于在多种土层的地基中,桩的计算是从试验出发,考虑了影响桩承载力的多种因素,首先假定土的抗力数学模型,用优化方法求取模型中的待定参数,由此将计算得到的结果用于同类型地基的桩基计算中。Basing on the relation of soil-pile interaction and related tests, the article analyses the computation of the piles in various soil layers, with various influences on the capacity of piles accounted. Moreover, the article presents a model of soil resistance, and then applies optimization method to estimate the parameters of the proposed model. The results are successfully employed in the design of pile foundations in like geological conditions.
