公路工程环境的岩土勘察与地质灾害评估技术研究

Geotechnical Investigation and Geological Hazard Assessment Technology for Highway Engineering Environment

采用层次分析法,对某公路工程岩土勘察与地质灾害评估技术进行了研究。通过对该地区公路地质层的岩石性质、地区整体地形地貌、地质水文等条件进行了相关实地调查,并对各影响因素进行了相应分析;对该地区公路地质所造成的灾害危险性进行了评价;评价结果显示:本工程公路沿线地质灾害低度危险区总里程为14 km,占公路全长21. 87%;中度危险区域的总里程有34 km,占公路全长53. 13%;其中属于高度危险路段总里程数为16 km,占公路全长25. 00%,表明本工程公路沿线的地质灾害危险性总体上偏中度。

The analytic hierarchy process (AHP) is used to study the technology of geotechnical investigation and geological hazard assessment for a highway project.Through the field investigation and Study on the rock properties of the highway geological layer,the overall topography and landform of the area,the geological and hydrological conditions,and the corresponding analysis of the various influencing factors,the hazards caused by the highway geology in this area are evaluated;the evaluation results show that:the highway along the project The total mileage of the mild hazard area is 14 km,accounting for 21.87% of the total length of the highway;the total distance of the moderate hazard area is 34 km,accounting for 53.13% of the total length of the highway;and the total mileage of the high hazard section is 16 km,accounting for 25.00% of the total length of the highway,indicating that the geological hazard risk along the highway of this project is generally moderate.
