摘要
为确保长白山轨道工程的合理设计,文章以其勘察成果为基础,先开展工程区水文地质条件分析,再利用P×C法开展长白山轨道工程区的工程建设适宜性评价.结果表明:根据地下水埋藏条件,工程区地下水类型包括孔隙水(又可细分为松散岩类孔隙潜水和松散岩类层间承压水)、玄武岩孔洞裂隙水,且工程建设主要对玄武岩孔洞裂隙水有较大影响.经工程建设适宜性评价,其整体适宜性得分为 90.80分,工程建设适宜性等级为Ⅳ级,即项目区的工程建设适宜性很好.文章的研究可以为长白山轨道工程后续设计提供一定的理论支撑,具有较强的现实意义.
Abstract
In order to ensure the rational design of Chang-baishan track engineering,based on the survey results,this paper first analyzes the hydrogeological conditions of the engineering area,and then uses the P×C method to carry out the engineering construction suitability evaluation of Changbaishan track engineering area.The results show that according to the groundwater burial condition,the types of groundwater in the engineering area include pore water(which can be subdivided into loose rock pore phre-atic water and loose rock interlayer confined water)and basalt pore crevice water,and the engineering construction mainly has a great influence on basalt pore crevice water.Through the suitability evaluation of engineering con-struction,the overall suitability score is 90.80 points,and the suitability grade of engineering construction is grade IV,that is,the suitability of engineering construction in the project area is very good.The research of this paper can provide some theoretical support for the follow-up de-sign of Changbaishan track engineering,which has strong practical significance.
