摘要:
首先根据楔形桩的受力特性,提出了楔形桩单桩破坏模式,然后从极限平衡理论出发,利用库仑土压力的推导思路,推导得到了该破坏模式下的楔形桩承载力计算方法; 将数值分析的结果与自编的单桩承载力计算程序计算得到的结果进行对比分析,验证了该方法的合理性。结果表明:其他参数不变时,在一定范围内增大楔形桩的锥角,可显著提高楔形桩的极限承载力; 当外摩擦角较大时,粗糙的桩侧面也可以提高楔形桩的承载力; 楔形桩尺寸也是影响单桩承载力的重要参数; 该方法在工程实际中有着较强的适用性。
Abstract:
Failure mode of single pile was derived based on the mechanical behavior of tapered pile. On the basis of the Coulomb's earth pressure theory, a new calculating method of bearing capacity of tapered pile under this failure mode was developed by utilizing limit equilibrium theory. Then, through the comparison of numerical analysis results with results obtainded by using self-made program, the rationality of this method was proved. It shows that the ultimate bearing capacity of tapered pile increases significantly with the increase of cone angle within a certain extent. Rough pile side is also used to increase the bearing capacity of tapered pile when the external friction angle is larger correspondingly. The size of tapered pile has important influence on the bearing capacity. It seems that this new method has good feasibility in engineering practice.
