采用 Morgenstern-Price 极限平衡理论对某水电站的泥石流沟边坡在各工况下的稳定性进行了分析。结果表明, Morgenstern-Price法能很好地描述泥石流沟边坡在治理前后的滑移形态与安全系数;原始边坡安全系数较小,可以通过增加拦水坝后压重的方式保证边坡的稳定;渗流对边坡的稳定影响较大,需采取措施尽量降低坝后浸润线的高度。可供类似工程借鉴。
採用 Morgenstern-Price 極限平衡理論對某水電站的泥石流溝邊坡在各工況下的穩定性進行瞭分析。結果錶明, Morgenstern-Price法能很好地描述泥石流溝邊坡在治理前後的滑移形態與安全繫數;原始邊坡安全繫數較小,可以通過增加攔水壩後壓重的方式保證邊坡的穩定;滲流對邊坡的穩定影響較大,需採取措施儘量降低壩後浸潤線的高度。可供類似工程藉鑒。

Based on the limit equilibrium method of Morgenstern-Price,the slope stability of debris flow gully in a power station was analyzed under the main conditions.It showed that the slide shape and the safety factor could be described well by the method of Morgenstern-Price. The safety of the original slope was poor,and the stability of the slope could be ensured by increasing the weight pressured on the back of the dam.In addition,the influence of the seepage on the slope was obvious. The height of the saturation line should be minimized.The results can be used as references for similar projects.
