Other Abstract
高陡边坡上的桥梁桩基(承重阻滑桩)具有承重与阻滑双重功能,其受力特性和变形特征比普通抗滑桩或竖向荷载桩复杂,采用极限分析上限定理,在假设滑面为通过坡趾下端的对数螺旋曲线的基础上,研究了不同荷载组合条件下加固边坡稳定性与承重阻滑桩所需提供的最小抗力之间的关系,阻滑桩设置位置对边坡稳定性与潜在破裂面的影响。并通过具体算例分析,得出了承重阻滑桩桩顶横向外荷载对边坡稳定有重要影响等一系列结论,对山区高陡边坡承重阻滑桩设计有指导意义。

The bridge pile foundation (Load-bearing and Anti-slide pile) in high-steep rock slopes has two functions, one is bears the load from the superstructure, the other is counteracts the landslide-thrust from the pile foundation side. The mechanical properties and deformation is much more complex than anti-slide piles and that of piles which under vertical load. According to the upper bound theorem of limit analysis and the logarithmic spiral curve, the relationship between the critical load provided by the pile and the safety factor of the slope, and the influence about the sliding surface and safety factor under the different position of the pile could be studied. Through analyzing the results, a series of conclusions about the stability of the slope under different combined loads and load methods are drawn, so as to guide the design of loading-bearing and anti-slide piles.
