Abstract
To achieve rational prevention and control of landslides,taking the landslide in Xuhuang formation,Zhifu village,Liuma town,Zhenning,Guizhou as the research background,this study first analyzed the development characteristics of the landslide,and then constructed a screening model for landslide prevention and control schemes using the Analytic Hierarchy Process(AHP),Critic method,and expert method to determine the optimal landslide prevention and control scheme.The analysis results show that the landslide is large in scale with clear boundary characteristics,and its main sliding surface is in an unstable state under rainstorm conditions,posing a high risk of instability,thus making it urgent to carry out further screening of prevention and control schemes.Meanwhile,the overall applicability scores of the"double-row anti-slide piles+cut-off and drainage"scheme and the"anti-slide piles+anchor cables+retaining walls+cut-off and drainage"scheme are 82.35 and 75.51 respectively,both with an applicability grade of Ⅳ(Grade Ⅳ),indicating that both are suitable for landslide prevention and control and can be considered as candidate schemes.In comparison,the"double-row anti-slide piles+cut-off and drainage"scheme has a relatively higher overall applicability score,meaning its prevention and control applicability is relatively higher.Therefore,the optimal landslide prevention and control scheme is determined as the"double-row anti-slide piles+cut-off and drainage"measure.关键词
