| 摘 要： | 针对工程实例,利用ABAQUS有限元软件建立单桩承载力的有限元计算模型,研究桩基承载特性,并与桩基静载试验所得实测数据比较。结果表明,模拟计算结果与工程实际基本吻合,说明采用的计算方法和模型是合理可行的。同时研究了在不同桩土界面摩擦系数条件下桩的沉降和轴向力变化情况,为不同工程地质条件的桩基设计提供参考。

Finite Element Analysis of Bearing Capacity of Pile Foundation |
| |
| Abstract: | On account of practical case,finite element calculation model of single pile bearing capacity is established with ABAQUS to study the bearing characteristics of pile foundation and compare with actual measurement data of static loading test of pile foundation.The result shows that simulated calculation result is basically consistent with actual engineering,which indicates that the adopted calculation method and model are reasonable and feasible.Meanwhile,the change of settlement and axial force of pile under different frictional coefficient of pile soil is studied,providing references for pile foundation design in different engineering geological conditions. |
