摘要
本文提出有限元-无限元耦合单桩弹性分析法,阐述了耦合分析的基本原理,并将耦合分析结果与有限元和积分法结果进行了对比分析,表明耦合方法具有计算精度高,计算时间省的特点。本文最后通过一个实例分析,将理论分析结果与试桩的实测结果进行了分析对比,表明耦合方法能对桩的弹性性状作出较好地预见,同时表明,在对桩身沉降和内力进行分析时,考虑桩周土层的非均质性是重要的。
This paper presents a method for elastic analysis of a pile which is based on the combina- tion of the finite element method with the infinite element method.Compared with the finite el- ement method,the analytical method developed in the paper has good accuracy and gives large savings in time and expense. The analytical results is compared with those from pile load tests.It is shown there is good agreement between observed and predicted results,it also can be seen that it is important to con- sider nonhomgeneous soil around a pile shaft in predicting the settlement and axial load of a pile.
