摘要
以临大公路K181+840～K182+040段滑坡为工程背景,在对该段滑坡进行现场地形地貌、气象条件、地层岩性、水等影响滑坡因素勘察的基础上,阐述了临大公路K181+840～K182+040段滑坡发育的特征和稳定性影响因素,利用数值模拟软件FLAC3D建立滑坡模型分析得出该段滑坡中部至滑坡前缘最大滑移值为24.05cm。影响因素粘聚力值每增加2kPa,滑坡前缘位移减小区间在0.61cm～12.23cm之间。
The landslide of K181+840~K182+040 of Linda Highway is the engineering background.On the basis of on-site topography,meteorological conditions,stratum lithology,water and other factors affecting landslides,the Linda Highway was expounded.The characteristics of the landslide development and the factors affecting the stability of the K181+840~K182+040 landslide were analyzed by the numerical simulation software FLAC3 D.The maximum slip value from the middle of the landslide to the landslide front was 24.05 cm.Influencing factors Cohesion force For each 2 kPa increase in C value,the displacement of the landslide front edge is between 0.61 cm and 12.23 cm.
