天山公路地处高寒高海拔地区,研究区域涵盖了崩塌、滑坡、泥石流等多种地质灾害,其中崩塌作为突发灾害,严重影响了公路的正常运营以及人民的生命财产安全。本文根据野外考察与统计分析,选取地形地貌、岩性、坡体结构、地质构造以及气候作为因子对其发育规律以及变形失稳机制进行研究,对沿线崩塌体的失稳模式进行分类,总结出滑移、倾倒、坠落等3种失稳模式。为当地公路部门开展地质灾害防治工作提供科学依据。
The Tianshan Highway is located in the alpine region with high altitude. The study area covers a variety of geological disasters such as landslide, landslide and debris flow. Collapse as a sudden disaster seriously affects the normal operation of the highway and people’s lives and property. Based on the field investigation and statistical analysis, this paper studies the development law and the mechanism of deformation and instability by selecting topography, lithology, slope structure, geological structure and climate as the factors, and classifies the instability modes of the collapsed bodies along the line, Slip, dump, fall, etc. 3 kinds of instability mode. Provide the scientific basis for the local highway departments to carry out geological disaster prevention and control work.
