路线基本走向的选择,关系到路线的全局;路线每一分部方案的优选,直接影响到工程的质量和造价,工程水文地质对某些方案的取舍,有决定的意义。对于高等级公路的前期工作应充分地考虑工程地质、水文地质对选线的影响。本文就连霍国道主干线洛阳——三门峡段在前期工作中工程水文地质所产生影响进行了评价,提出了一些具体解决方法以及选线决策人员应给予特别重视的因素。
The selection of the basic direction of the route is related to the overall situation of the route. The optimization of the program of each branch in the route directly affects the quality and cost of the project. The selection of engineering hydrogeology for certain options has a decisive meaning. The preliminary work on high-grade highways should fully consider the impact of engineering geology and hydrogeology on the route selection. This paper evaluates the impact of the hydrogeology of the Luoyang-Sanmenxia section of the main trunk line of the Huo Guo Road in the preliminary work, and puts forward some concrete solutions and the factors that the decision-makers of the line selection should pay special attention to.
