基于湘西地区典型红层滑坡应急工程设计探讨

Based on the typical red-floor landslide emergency engineering design in Western Hunan

湖南省湘西地区地形起伏大,地质条件复杂,地质灾害较发育。随着近年极端天气多变,暴雨时期逐年增加,区内山地、丘陵一带的崩塌、滑坡等地质灾害成突发事态,造成财产损失逐年增加。本文以湘西地区山体滑坡为例,总结区内小型滑坡应急治理工程技术,建议区内红层滑坡易发地区以降雨预警为主,后期治理工程以应急治理为主,及时减灾防灾。

Xiangxi area of Hunan province has large topographic relief,complicated geological conditions and developed geological hazards.With the changeable extreme weather in recent years,the period of rainstorm increases year by year,and geological disasters such as collapse and landslide in the mountainous and hilly areas of the region become emergencies,causing property losses to increase year by year.Taking the landslide in Western Hunan as an example,this paper summarizes the emergency control engineering techniques for small landslides in the region,and suggests that the red-layer landslide prone areas in the region should give priority to early warning of rainfall,and the later stage of the control project should be given priority to emergency control and timely disaster reduction and prevention.
