摘要
运用ABAQUS软件对桩土结合模型进行了数值仿真.利用ABAQUS中的主-从接触算法,在桩身与土体之间建立接触对,对桩身采用弹性模型,土体采用扩展的Drucker-Prager模型进行模拟,并考虑初始地应力的影响.通过计算得到竖向载荷作用下桩的轴力分布曲线和沉降曲线.在算例中模拟了江苏某大桥N1号试桩,结果与现场实测值相近.
In this paper, ABAQUS sottware is used to simulate interaction between pile and soil. The pue-son contact pair is built by the master-slave method. The model of pile is elastic, and modified Drucker-Prager elastic-plastic model is applied to soil. The initial stress is also considered. For example,the N1 test-pile of a bridge is simulated. And the axial forces and settlements of the pile under the top loads are given. The results show that ABAQUS is available for simulation of pile-soil interaction.
