某面板堆石坝，边坡加固一期工程主要对坡脚进行护岸开挖和回填混凝土压脚，二期工程在一期工程的基础上削坡减载卸荷。采用数值模拟的方法对边坡进行了稳定性分析，同时引入数理统计方法对塑性区变化进行了定量分析，结果表明：与一期工程相比，二期工程塑性区明显减小，二期工程加固后塑性区较一期工程减少了1/4强；二期工程边坡加固是有效的。

The way of reinforcement of a rock fill dam slope includes the slope excavation and backfilling concrete pressure foot are involved in the first stage. In the second stage,slope cutting and unloading is brought in on the basis of the first stage. This paper made a detailed analysis of the stability of the slope by using the numerical simulation method. Then quantitative analysis was applied to analyze plastic zone changes. The result shows that comparing with the first phase of the project,the plastic zone is obviously reduced to slightly more than a quarter. The stage Ⅱ of the project slope reinforcement is effective.
