| 青海省是我国滑坡地质灾害比较严重的地区之一。湟源县滑坡分布广泛且具有时空集中性,给当地人民生命财产安全和工程建设带来了极大的威胁,因此加强对滑坡稳定性的认识和防治十分必要。本文以纳隆村滑坡为研究对象,结合勘查钻探等资料,利用瑞典条分法对P5剖面进行稳定性计算,计算出天然、暴雨、地震3种工况下的稳定性系数。经稳定性计算分析,滑坡在暴雨工况下整体处于欠稳定状态；在地震工况下滑坡整体处于不稳定状态,对前缘纳隆村村民带来较大危害。成果为该滑坡治理决策提供理论支撑。 |
| 英文摘要: |
| Qinghai Province is one of the areas with serious landslide geological hazards in China. The landslide in Huangyuan County is widely distributed and centralized in time and space, which poses a great threat to the safety of people's lives and property and the construction of the project. Therefore, it is necessary to strengthen the understanding and prevention of landslide stability. Taking Nalong village landslide as the research object, combined with exploration and drilling data, the Swedish slice method is used to calculate the stability of P5 section, and the stability coefficients under natural, rainstorm and earthquake conditions are calculated. Through stability calculation and analysis, the whole landslide is in an unstable state under rainstorm condition, and the whole landslide is in an unstable state under earthquake condition, which brings great harm to the villagers in Nalong village. The results provide theoretical support for the decision-making of landslide control. |
