钻(挖)孔灌注桩单桩承载力三维数值分析

3D numerical analysis of single-pile bearing capacity of bored cast-in-situ pile

利用ANSYS软件按桩侧表面积等效法建立了三维单桩承载力数值分析模型,并推导了一种简便的计算摩擦系数公式,同时给出了ANSYS软件用来模拟桩土共同作用各计算参数的确定方法;结合工程实例并与实测结果比较表明,该法具有一定的仿真效果和计算精度。

This paper sets up 3D numerical analysis model of single-pile beating capacity by using ANSYS software and according to pile-side surface-area equivalent method, deducts a simply formula to calculate frictional coefficient, proposes the method to confirm each computing pararneter to simulate pile-soil combined activity by ANSYS software, and shows that , combined with engineering instance and compared with field measuring results, this method has certain simulation effect and computing accuracy.
