摘要: 运用ANSYS软件,从桩身轴力、桩侧摩阻力和静载荷曲线三个方面对后注浆灌注桩的荷载传递特性进行数值模拟,并与工程实例对比分析,为灌注桩设计和施工提供依据,为提高灌注桩的承载力提供参考。Abstract: Using ANSYS software,,it was simulated and analyzed the load transfer characteristics of post-grouting bored piles from the following three aspects: the pile axial force,pile side friction and static load curve,and the results were compared and analyzed with that for project example.The results provide an evidence of the pile design and construction,and also have a certain reference for enhancing the bearing capacity of pile a bored.
