摘要
广西地区岩溶现象十分发育,该文以金城江水电站工程为例,阐述了在坝址区工程地质前期勘察中,使用地质测绘、高密度电法、钻探、电磁波CT等手段相互配合,查明了工程区的岩溶分布情况和发育程度,并分析了其对坝址选线的影响及对推荐坝线的不良地质影响,为坝址选线提供了科学依据。
The karst phenomenon is very developed in Guangxi.Taking the Jinchengjiang Hydropower Station project as an example,this paper expounds the application of geological mapping,high-density electrical method,drilling,electromagnetic wave CT and other means in the preliminary engineering geological survey of the dam site area,the karst distribution and development degree are found out in the project area,and its impact on the dam site selection and adverse geological effects on the recommended dam line are analysed.It provides a scientific basis for route selection of dam site.
