基于传递系数法和变形预测的双层滑带滑坡稳定性的综合评价
Comprehensive evaluation of stability of double-layer sliding belt landslides based on transfer coefficient method and deformation prediction
摘要
Abstract
This paper is meant to effectively obtain the basic characteristics and stability of double-lay-er sliding belt landslides.Based on the geological conditions of this type of landslide with its basic charac-teristics and deformation characteristics,combined with deformation monitoring results,the study compre-hensively evaluates its stability through the transfer coefficient method and deformation prediction.The re-sults indicate that the double-layer sliding belt landslide has the characteristics of more complex structure,relative movement between zones,significant differences in material composition,thicker sliding body,and generally larger scale.Meanwhile,through the transfer coefficient method with the stability coefficient of the shallow sliding surface from 1.041 to 1.428,and the stability coefficient of the deep sliding surface from 1.027 to 1.268,the landslide is in an unstable state and has a significant risk of instability under ad-verse working condition.Through deformation prediction,the subsequent stability of DJ1 and DJ2 monito-ring points will generally maintain the current situation,while the subsequent stability of DJ3 monitoring points will tend to weaken,and thus,the local stability of the landslide tends to develop in an unfavorable direction,and its prevention and control measures need to be carried out as soon as possible.关键词
