以舟曲泄流坡滑坡野外考察地质资料为基础,结合滑坡动力分析软件DAN-W对泄流坡滑坡全程运动进行模拟,着重探讨了铲刮效应以及不同流变模型对滑坡数值模拟的影响.结果表明：不同铲刮深度下,滑坡堆积体形态相似,堆积厚度随铲刮深度的加深而加大,运行时间随铲刮深度的加深而减少. F-V模型对泄流坡模拟的滑程最大可达255.75 m, Frictional模型模拟得到的最大堆积厚度为201.73 m,最大前缘速度为17.75 m/s,最长运行时间为64 s,并给出了泄流坡滑坡模拟最佳的流变参数,摩擦角为18?,摩擦系数为0.1,湍流系数为1000 m/s2.

Based on field survey geological data of the Xieliupo landslide in Zhouqu and combined with landslide dynamic analysis, the software DAN-W was used to simulate the motion of the Xieliupo landslide, and to explore the impact on landslide numerical simulations about the erosion effect and different rheologies. The results showed that the landslide deposit forms were similar to different erosion depths and stacking thickness along with the increase in erosion depth but decrease in running time. The maximum movement distance was 255.75 m simulated by F-V model. The maximum thickness was 201.73 m, the maximum front velocity was 17.75 m/s and the longest movement time is 64 s simulated by Frictional model. The best suitable rheological parameters have been found to simulate this landslide, with the friction angle being 18?, friction coe?cient being 0.1 and turbulence coe?cient being 1 000 m/s2.
