贵州纳雍骔岭镇危岩带稳定性及危害范围分析

Analysis on stability and hazard zone of dangerous rock mass in Zongling Town,Nayong of Guizhou Province

骔岭集镇—大箐脚一带危岩为喀斯特地区典型的缓倾层状危岩,由于自然环境脆弱,在受岩溶地质、人工活动、降雨诱发等多种因素作用下形成,具有单体规模大、带状长度大、崩落距离远、影响人数多之特点。基于危岩的稳定性及危害分析的基础上,划分危岩崩塌严重影响区及监测预警避让区,对喀斯特地区典型的缓倾层状危岩地质灾害隐患点的早期识别与防范,提高防灾减灾工作的认识具有理论与现实的意义。

Angerous rocks in Zongling County-Dajingjiao are typical dangerous rocks in karst areas.karst geology,human activities rainfall etc.Characterized by large scale,large strip length,long distance of collapse,and large-scale.Based on the stability and hazard analysis of dangerous rocks divide the severely affected area of collapse and the monitoring and early warning avoidance area,which has theoretical and practical significance for the early identification and prevention of geological hazard of typical dangerous rocks in karst areas.
