摘要
由于西部地区地形、地貌、地质的复杂、多变性,导致山区高速公路勘察、设计难度大,需要考虑的因素多,技术要求高,设计单位都意识到地质选线在山区公路建设中的重要性。目前研究山区地质选线的学者较多,但对于构造地质选线的研究较少。设计中由于对构造地质的认识不足及不全面,引发的设计变更不在少数,凸显研究构造地质选线的必要性。结合罗望高速、金仁桐高速、昆楚高速、惠罗高速,归纳总结了构造地质选线的工作核心点,创新性提出影响山区高速公路建设的地质构造类型及构造地质选线原则。
Due to the complexity and variability of topography,geomorphology,geology,and bad geology in the western areas of the country,it usually faces various difficulty when carry out survey and design of such mountainous expressway,needing to consider multiple factors,especially the stringent technical requirements.All designers have come to aware of the importance of geological selection in the construction of mountain highways.At present,there are many scholars studying the geological line selection of mountainous areas,but few researches on the tectonic geological line selection.Due to insufficient and incomplete understanding of structural geology in the design,variation is normal during construction.Therefore,it is necessary to study tectonic geological line selection.Combined with the Luodian-Wangmo Expressway,Jinsha-Renhuai-Tongzi Expressway,Kunming-Chuxiong Expressway,and the Huishui-Luodian Expressway,the core points of tectonic geological line selection are summarized and concluded.The structural types and tectonic geological line selection principles that affect the construction of mountain expressways are innovatively proposed.
