摘要

贵州省地处喀斯特地区,岩溶、断层等不良地质现象发育,地质条件复杂,而地质条件又是建坝成败的决定因素之一,因此水利水电工程建设要求在勘察阶段查明坝址各种不良地质现象的发育、分布、规模情况。因受投资经济性的制约,大坝选址往往位于河床狭窄的深山峡谷中,因此针对坝址顺河隐伏断层的勘察,采用地震CT技术,已成为一种重要的勘查手段。文章将结合道真县角木塘水电站工程实例,介绍地震CT技术在坝址河床隐伏断层勘察中的应用。
Guizhou Province is located in the karst area,along with the development of karst faults and bad geological phenomenon,and complicated geological conditions which is one of decisive factors for building a dam successfully. Therefore it required for hydraulic engineering to identify various adverse geological phenomena such as its development,distribution and scale. Restrained by cost and other factors,the dam site is selected at the narrow canyon of a riverbed,hence earthquake CT is used to investigate the burred faults of the dam site and it has become an important measure for the dam site investigation. Taking Jiaomutang Hydropower Station as an example,the application of earthquake CT in the investigation of dam site burred faults is introduced in the paper.
