摘要:: 济南至莱芜高速铁路穿越济南白泉和玉河泉泉群流域,如何避免对济南白泉和玉河泉群的影响,是本线亟待解决的问题。本文基于济莱高速铁路岩溶水文地质专题研究和岩溶隧道地质勘察资料,阐述了济南至莱芜高速铁路通过地段的岩溶水发育特征、岩溶水补、径、排条件,划分了沿线岩溶含水岩组及水文地质单元,分析了济南泉群形成机理,评价了铁路工程对济南泉群影响,结果表明,济莱高速铁路济南段工程地质线路方案选线、工程设置比选,较好规避了铁路工程建设对济南著名泉点的影响。

Abstract:: Considering Jinan-Laiwu High-speed Railway passes through Baiquan and Yuhe Spring Group in Jinan, how to avoid the impact on Baiquan and Yuhe Spring Group in Jinan is an urgent problem to be solved. Based on the special study on karst hydrogeology of Jinan-Laiwu High-speed Railway and the geological survey data of karst tunnels, this paper elaborates on the development characteristics of karst water, karst water replenishment, runoff, and drainage conditions in the section through which Jinan-Laiwu High-speed Railway passes, divides karst water-bearing rock formations and hydrogeological units along the line, analyzes the formation mechanism of the spring groups in Jinan, and evaluates the impact of railway engineering on the spring groups in Jinan. The results show that the route selection and engineering setting comparison of the engineering geological route scheme of the Jinan section of Jinan-Laiwu High-speed Railway can avoid the impact of railway construction on famous spring points in Jinan.
