承重阻滑桩受力特性分析

摘要

Load-bearing and anti-slide pile has been widely used in construction of expressways and towns; I has double function of bearing, its mechanical characteristics are much more complicated than anti-slide pil and tilt load pile in horizontal ground. This article calculates the three kinds of condition effecting load-beai ing and anti-slide pile internal force of pile head load, groundwater level height and seismic load by the whol finite element method. Through analyzing the results, a series of conclusions are drawn, so as to guide th design of load-bearing and anti-slide piles.%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.
