| 摘 要： | 位于边坡顶面上的建（构）筑物桩基,具有承重和阻滑双重功能,又兼有抵抗水平荷载或倾斜荷载作用,其受力性状远比边坡内部的抗滑桩、水平地面上的横向受荷桩或倾斜受荷桩复杂。在综合分析和评价国内外组合受荷桩研究工作的基础上,分析了坡顶斜向受荷桩独特的受力特点,从而将其分为自由段、受荷段、嵌固段3个特征桩段,在此基础上,综合考虑p-△效应、滑坡推力、地基系数、桩身侧摩阻力、桩身自重等影响因素,建立了各特征桩段的微分方程。基于＂m＂法,采用矩阵计算方法,得到单桩计算分析的幂级数解答,并通过实例分析表明该方法准确方便。

| Abstract: | The inclined loaded piles located near slopes have a popular application in modern urban civilization and communication construction. The piles are used to both reinforce the slope near the construction and carry the superstructure-induced loading and the additional lateral loading. The bearing performance of the piles becomes much more complex than stabilizing piles against landslide or inclined-loading piles. Based on comprehensive analysis and evaluation of the reaearch work on pile under assembled loads... |
