公路地质灾害的影响因素很多,这些因素相互联系、相互制约。经过研究,公路地质灾害中,滑坡和崩塌灾害的影响因素主要有地形地貌条件、地质构造、岩土类型等内在因素和降雨洪灾、人类活动~[3]等外在因素;公路泥石流灾害的影响因素主要有地形地貌、岩土类型、地质构造等内因和降雨等诱因;而公路土壤膨胀变形的主要影响因素则为温度、地表地下水、施工方法和行车的作用。
There are many influencing factors of highway geological disasters, these factors are interrelated and mutually restrained. After the study, among the geological disasters in the highway, the main influencing factors of the landslide and collapse are the external factors such as the topography and geomorphology, geological structure, geotechnical types and other internal factors, rainfall and floods, and human activities [3]; the influence of debris flow hazards The main factors are topography, geotechnical type, geological structure and other internal causes and rainfall; and the main factors affecting the highway soil deformation are temperature, surface groundwater, construction methods and traffic.
