地质选线就是在对路线所处的工程地质环境进行综合调查,分析研究公路工程与工程地质环境之间相互制约、相互影响、相互作用规律的基础上,趋利避害,合理利用工程地质环境,选择路线方案的过程。本文结合扬州至绩溪高速公路宁国至绩溪段初步设计路线方案选定的过程,总结出如何利用1∶1万遥感地质图并结合地质调绘,对明显的地质病害进行过滤筛选,对那些病害规模大、处治困难的病害地段加以避让。
Geological alignment is based on a comprehensive survey of the engineering geological environment in which the route is located. Based on the analysis of the laws governing the mutual restraint, interaction and interaction between the highway engineering and the engineering geological environment, it is advantageous to avoid disadvantages and make rational use of the engineering geological environment , Choose the course of the program process. Based on the selection of the preliminary design route from Ningguo to Jixi in Yangzhou to Jixi Expressway, this paper summarizes how to use 1: 10000 remote sensing geological map combined with geological mapping to filter the obvious geological diseases, Large, difficult to deal with the disease to avoid the lot.
