After getting identical results between numerical analysis and model experiment,this paper analyzes and builds an expression between the least pile length embedded in rock and horizontal load and modules ratio of rock,draws a conclusion that load limit can be decided through the curves of displacement ratio,and discusses the functions of both the least pile length and the expression.
本文在建立数值模型并取得与模型试验结果有较好吻合的前提下,分析并拟合了最小嵌固深度与水平荷载和模量系数之间的关系式,得出了利用数值分析得到的位移比率曲线可判断桩的极限荷载的结论,同时对最小嵌固深度及其计算式的作用进行了讨论。
