贵州省湄潭县地质灾害孕灾因素分析及防治对策

ANALYSIS ON THE FACTORS OF GEOLOGICAL HAZARD AND COUNTERMEASURES IN MEITAN COUNTY OF GUIZHOU PROVINCE

为更好总结湄潭县地质灾害孕育规律及指导湄潭县今后的地质灾害防治工程,在分析现状地质灾害发育特征及地质灾害孕育因素的基础上,重点从坡度、地质构造、岩土体类型、斜坡结构、地表水因素、地下水因素进行分析,运用ARCGIS软件进行孕灾分区。将全县划分为易孕灾区、中易孕灾区、一般孕灾区,针对不同分区就不合理切坡管控、地质灾害宣传及培训、地质灾害及风险斜坡排查与预警监测提出相应的防治建议。

In order to summarize the geological hazard breeding law of Meitan County and guide the geological hazard prevention project of Meitan County.Based on the analysis of the development characteristics of the current geological hazard and the geological hazard preparation factors,the paper analyzes the slope,geological structure,rock and soil mass type,slope structure,surface water factors and groundwater factors,and uses the ARCGIS software to carry out disaster preparation zoning.The whole county is divided into pregnancy prone geological hazard areas,moderate pregnancy prone geological hazard areas and general pregnancy prone geological hazard areas,and corresponding prevention and treatment suggestions are provided for the management and control of unreasonable slope cutting in different districts,the publicity and training of geological hazard,the investigation and early warning monitoring of geological hazard and risky slopes.
