摘要
建立典型边坡的桩-土-边坡相互作用数值模型,提出强度折减法新判据的公式,研究抗滑桩设置于边坡下部、中部、上部3种不同位置对边坡稳定性的影响,探寻了边坡临界状态失稳破坏机理,验证了位移突变倍率判据在抗滑桩加固边坡三维数值分析中的实用性、准确性,为抗滑桩合理桩位设置研究提供理论支撑。
The paper is established a typical slope numerical model considering pile-soil-Slope interaction,and proposed strength reduction new criteria formula.The influence of the location of anti-slide piles on the stability of slope is studied via setting the pile at the lower,middle and upper part of the slope.The critical state of slope failure damage mechanism is explored.The paper is also to verify the displacement mutation rate criterion in the edge reinforced with piles numerical analysis of slope in the practicality,accuracy.Finally,a reasonable method of setting the anti-slide pile location is provided based on theoretical research.
