摘要
望谟县石屯镇翁村一组崩塌(危岩体)地质灾害是碳酸盐岩地区主要的地质灾害之一,通过对区内危险性较大危岩带及5处危岩体发育情况进行地质环境调查分析,得出崩塌区地质灾害的形成原因,预测地质灾害发展趋势,采用赤平投影对危岩带稳定性进行定性分析,按危岩体的破坏模式计算其稳定性,模拟分析崩塌落石运动轨迹,开展综合分析、评价,提出崩塌(危岩体)的防治建议,为治理工程设计提供可靠依据。
The geological disasters of collapse(dangerous rock mass)in Weng Village Group 1,Shitun Town,Wangmo County is one of the main geological disasters in carbonate areas.Through geological environment investigation and analysis of the development of dangerous rock belts and five dangerous rock masses in the area,the causes of geological disasters in the collapse area is obtained,and the development trend of geological disasters is predicted.Qualitative analysis of the stability of dangerous rock belts is carried out using stereographic projection,and its stability is calculated according to the failure mode of dangerous rock masse,simulate and analyze the movement trajectory of collapsed rockfalls,and carry out comprehensive analysis and evaluation.Suggestions for the prevention and control of collapse(dangerous rock mass)are put forward,and provide a reliable basis for the design of treatment engineering.
