摘要
P-Y曲线法是一种研究水平受荷桩特性的常用方法,通过P-Y曲线结合有限元工具可以得到水平受荷桩在不同水平荷载作用下的桩顶位移。本文基于P-Y曲线理论并借助有限元工具,建立了黏土下考虑土层参数的单桩水平承载力参数计算公式,并在实际工程中将此方法与我国桩基规范计算方法和原位基桩水平静载试验结果进行对比,验证了该种方法的有效性与准确性。
P-Y curves method is one kind of common ways to do research on the characters of laterally loaded pile.And combined with finite element method,the lateral displacement at pile top can be achieved.Based on P-Y curves and finite element method,considering the soil parameters,the computational formulas of lateral bearing capacity of single pile in clay is built.In engineering practice,this method is compared with the code for pile foundation in China and lateral static load test results,which demonstrates the effectiveness and accuracy of this method.
