德钦县楚巴崩塌特征分析及防治措施研究

Study on the Characteristics and Prevention Measures of Chuba Landslide in Deqin County

对澜沧江左岸楚巴崩塌斜坡区的地质环境条件进行了详细调查,采用地质测绘、山地工程及试验分析等方法,分析了此次崩塌的危岩体、基座及堆积等发育特征。通过定性分析和数学计算,对各危岩体的稳定性进行了综合评价,查清了危岩破坏模式和威胁范围,针对风险较高的危岩,结合工程实施条件,提出了“拦石墙+拦石网+人工清危+主动防护网”的方案进行防治,对楚巴崩塌发育特征进行分析并研究防治措施,为该类崩塌的避险与工程治理提供设计参考。

This article conducts a detailed investigation into the geological and environmental conditions of the Chuba landslide slope area on the left bank of the Lancang River.It employs methods such as geo-logical mapping,mountain engineering,and experimental analysis to examine the development character-istics of the landslide's dangerous rock masses,foundations,and accumulations.Through qualitative a-nalysis and mathematical calculation,the stability of each dangerous rock mass is comprehensively evalu-ated,identifying the failure modes and threat ranges of the dangerous rocks.For high-risk dangerous rocks,a prevention and control plan combining“stone blocking wall,stone blocking net,manual hazard removal,and active protective net”is proposed based on engineering implementation conditions.The a-nalysis of the development characteristics of the Chuba landslide and the study of prevention and control measures provide design references for the risk avoidance and engineering treatment of such landslides.
