在实地踏勘的基础上,对云南泸水县国门小学滑坡的地质地貌条件以及滑坡体的基本特征进行了详细的分析。在此基础上,运用极限平衡理论对该滑坡的公路段以及整个滑坡体,分3种工况进行了稳定性研究。结果表明:在较为干燥的条件下,各段滑坡体均处于稳定状态,但在强降雨或是地震工况下,则表现为基本稳定-欠稳定状态。为了防止地质灾害发生,结合相关理论提出了治理方案,建议实施支挡和排水工程。
Based on the site survey, the geological and geomorphological conditions of the landslide in Lugu County, Yunnan Province and the basic characteristics of the landslide body are analyzed in detail. On this basis, using the theory of limit equilibrium, the stability of the highway section and the whole landslide body in three conditions is studied. The results show that the landslides are in steady state under relatively dry conditions, but they are basically stable under unstable rainfall or earthquake conditions. In order to prevent the occurrence of geological disasters, combined with the relevant theories put forward the control plan, it is recommended to implement the support and drainage projects.
