摘　　要：泸州至古蔺高速公路(以下简称泸古公路)沿线工程地质环境兼具复杂的地质背景、褶皱构造发育、不良地质发育、环境敏感点多等特征,孕育着诸多影响公路建设的工程地质问题。研究发现:影响拟建公路建设的主要工程地质问题包括高位危岩落石及崩塌灾害、滑坡灾害、不稳定斜坡、顺层边坡、褶皱构造带、有害气体及生态环境敏感等七大问题。针对上述工程地质问题,提出了上述地质风险管控的对策思考,建议以先进科学研究理论为指引,细致调查及钻探验证为基础,辅以数字化钻探新技术、无人机航拍、微动探测、航空物探等新高新技术手段,有针对性的进行不同灾害的对策研究,促进对拟建公路沿线主要工程地质问题及其对工程建设影响的认识提升,实现安全、经济、绿色选线目标。The engineering geological environment along Luzhou-Gulin Expressway(hereinafter referred to as Lugu Highway) is characterized by complex geological background,fold structure development,bad geological condition,and many sensitive points,which are pregnant with many engineering geological problems affecting highway construction.The main engineering geological problems affecting the proposed highway include seven major problems,such as rock fall and collapse disaster of high dangerous rock,landslide disaster,unstable slope,bedding slope,fold tectonic belt,harmful gas and fragile ecological environment.In view of the above engineering geological problems,the countermeasures,including detailed investigation and drilling validation,supplemented by new digital drilling technology,UAV aerial photography,micro-motion detection,aerial geophysical exploration and other new technical means are suggested on the basis of the advanced scientific research theory.Targeted countermeasures of different disasters should be studied to promote the awareness of the main engineering geological problems along the proposed highway and their impact on the project construction,so as to achieve the goal of safe,economic and green route selection.
