摘　　要：以Geddes弹性应力解为基础,充分考虑土的空间应力分布,根据土的Duncan-Chang非线性应力-应变模型,通过弹性理论基本方法计算竖向荷载作用下人工挖孔桩的单桩沉降。计算方法简单且计算结果合理准确,适合工程应用。Based on Geddes stress solution and considering space dimensional stress of soil, according to the nonlinear elastoplastic model of Duncan - Chang, base on the flexible theories basic method ,it can calculate the settlement of single Manpower Excavation Pile with enlarge bases under vertical loads. Calculation method is simple and the accuracy is higher, it is suitable for engineering application.
