摘要
鉴于抗滑桩加固边坡设计中存在诸多不确定性因素,针对抗滑桩加固边坡案例提出了一种基于可靠理论的边坡系统抗滑力的分析模型,并结合代表性滑动面原理建立了相应的求解方法。算例分析表明,抗滑桩对边坡的代表性滑动面的位置及可靠度指标有着重要影响。在抗滑力相同的条件下,抗滑桩存在一个最优的加固位置,所提方法可确定抗滑桩的加固位置和抗滑力,对抗滑桩加固边坡的最优设计具有参考意义。
In view of many uncertain factors in the design of anti slide pile reinforced slope,an analysis model of anti slide force of slope system based on reliability theory is proposed for the case of anti slide pile reinforced slope,and the corresponding solution method is established combined with the principle of representative sliding surface.The example analysis shows that the anti slide pile has an important influence on the position and reliability index of the representative sliding surface of the slope.Under the condition of the same anti slide force,the anti slide pile has an optimal reinforcement position.The proposed method can determine the reinforcement position and anti slide force of the anti slide pile,which has reference significance for the optimal design of the slope reinforced by the anti slide pile.
