结构的整体稳定在结构设计中非常重要。特别是对较高的加筋土墙，该文将重点对加筋土挡墙进行整体稳定性的可靠性分析，通过将加筋体看成一般重力式墙，用圆弧法得到护坡的最危险滑动面及中心点。并建立极限状态方程，运用MaⅡab中实现蒙特卡罗法的编程。基于加筋土结构整体稳定性的可靠性分析，具有明显的理论恚义和很大的实用价值。
結構的整體穩定在結構設計中非常重要。特彆是對較高的加觔土牆，該文將重點對加觔土擋牆進行整體穩定性的可靠性分析，通過將加觔體看成一般重力式牆，用圓弧法得到護坡的最危險滑動麵及中心點。併建立極限狀態方程，運用MaⅡab中實現矇特卡囉法的編程。基于加觔土結構整體穩定性的可靠性分析，具有明顯的理論恚義和很大的實用價值。

the integrated stability of structures is very important in the structural design, especially in higher reinforced retaining walls. This paper mainly introduces the reliability analysis of integrated reliability of earth retaining wall, based on treated the reinforcement as a gravity wall, to get the most dangerous sliding surface and center of the slope, and established the limit state equation, realized the Monte Carlo method programming with the Matlab. It shows the reliability analysis based on the overall stability of the reinforced earth structure has obvious theoretical significance and of great practical value.
