摘　　要：承重阻滑桩在山区高速公路建设及山区城镇建设中应用广泛,具有承重与阻滑双重作用,其受力性状远比抗滑桩和平地上受荷桩复杂.本文采用整体有限元法,对影响承重阻滑桩内力的桩顶荷载、地下水高程和地震荷载三类工况进行计算.通过对计算结果的分析探讨,得到一系列的结论,对承重阻滑桩的设计有一定的指导作用.Load-bearing and anti-slide pile has been widely used in construction of expressways and towns;it has double function of bearing,its mechanical characteristics are much more complicated than anti-slide pile and tilt load pile in horizontal ground.This article calculates the three kinds of condition effecting load-bearing and anti-slide pile internal force of pile head load,groundwater level height and seismic load by the whole finite element method.Through analyzing the results,a series of conclusions are drawn,so as to guide the design of load-bearing and anti-slide piles.
