摘要
针对某滑落填土边坡,在对其稳定性进行分析评价的基础上,采用恢复挡土墙并结合抗滑桩的方案进行支护.从原设计的挡土墙入手,采用反算法得出该挡土墙恢复后承担的临界土压力,再从桩、墙作用力的分摊效应方面考虑,应用抗滑桩的极限承载理论和绕流阻力理论及钢筋混凝土结构学知识进一步探讨了抗滑桩的合理设置,从而对该土质边坡,提出一套具有参考价值和针对性的边坡优化支护方案.
Based on the stability evaluation of a destroyed filling slope, a method of slope treatment with recovering retaining wall and combination with stabilizing pile is presented.First, by means of reversing arithmetic, a critical soil pressure is deduced from the former retaining wall. Then, from sharing effect of stabilizing pile and retaining wall, discussion about retional setting of stabilizing pile has also been studied by applying the theory of ultimate bearing capacity and circle resistance and architectonic knowledge of armoured concrete. Accordingly, a set of pertinent optimum designing method has been proposed with some reference significance for this soil slope.
