昆石高速公路K22滑坡稳定的离散元分析

昆明—石林高速公路(简称昆石公路)松茂滑坡位于K22+900~K23+180段。为确保该路段安全,对K22段滑坡进行抗滑桩处治。为了检验处治方案的合理性,利用离散元元模拟了滑坡处治前后的边坡稳定状况。离散元元分析结果表明,处治前的滑坡情况和现场实际情况比较吻合。对K22+900滑坡段施加抗滑桩的处治后的模拟结果表明,处治后的滑坡安全、稳定。

Analysis on BEM Stability of K22 Landslide on Kun-Shi Expressway

The Songmao slope is at the K22+900～K23+180 of the highway from Kunming to Shilin(Kun-Shi Expressway).In order to ensure the safety of the road,slide resistant piles are established to protect the slope.2D EM analysis is introduced to inspect the rationality of the treatment.The result shows that the slope is unstable without treatment,and the simulation result is very similar with the observed phenomena.The slope becomes stable and safe after treatment of slide resistant piles.It indicates that the method to treat the slope is reasonable and efficient.
