贵州甲定村后龙山危岩体稳定性评价及成因分析

Stability Evaluation and Cause Analysis of Houlongshan Dangerous Rock Mass in Jiading Village,Guizhou Province

贵阳甲定村后龙山高坡陡崩塌地质灾害频发,严重威胁村民生命财产安全。在对甲定村后龙山危岩体发育特征现场勘查基础上,通过定性分析及定量计算,综合评价得出该危岩体的稳定性较差;根据岩体内部结构、发育特征及所处地形地貌、地质构造、外部条件等多角度分析,最终判断崩塌危岩体的形成因素,为该隐患点下一步治理及类似崩塌地质灾害区的成因分析、防治提供经验。

The high slope of Houlongshan in Jiading Village,Guiyang is steep,and geological disasters such as collapse occur frequently,which seriously threatens the life and property safety of villagers.Based on the field investigation of the development characteristics of the dangerous rock mass of Houlongshan collapse in Jiading Village,the stability of the dangerous rock mass is poor through qualitative analysis and quantitative calculation comprehensive evaluation.According to the analysis of the internal structure and development characteristics of the rock mass,the landform,geological structure and external conditions,the formation factors of the rock mass at risk of collapse are finally determined,which provides experience for the next control of the hidden danger point and the cause analysis and prevention of similar geological disaster areas of collapse.
