摘要
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 area of high and cold altitude, and the study is conducted in terms of collapse hazards, landslide, debris flow and a variety of geological disasters. As unexpected disaster, the collapse hazards seriously threaten the normal operation of the highway and the safety of people＇s life and property. According to the field survey and analysis, in this paper landform, lithology, structure of slope, geological structure and climate factor as the influencing factors, the development rules of collapses and deformation and failure mechanisms are studied. On the basis of the characteristics of the collapse hazards, the failure mode of the collapsed mass are mainly slide, collapse, and fall down, which provides scientific basis for the local highway departments to carry out the geological prevention.
