摘要
结合实例讨论了物探在地质灾害探查和找水方面的应用。在温峡口水库渗漏探查中,采用无线电波透视和充电法,成功地圈定了漏水通道。在乌江彭水坝址野猫洞去向探查中,用无线电波透视法查明了埋深近百米的溶洞通道的去向。葛洲坝二江上游围堰渗漏,用自然电场法准确查明了漏水的部位。在第四系找水方面,介绍了直流电测深法的两个应用实例。最后讨论了物探在地质灾害探测及找水等方面应用中需注意的几个问题。
Abstract
With case studies this paper deals with the application of geophysical prospecting to geologic calamity investigation and water exploration.
During the leakage investigation of the Wenxiakou reservoir, radio wave penetration method and 'mise-a-la-masse' method were successfully used to locate leakage channel; during the investigation of the dirsction of Yemaodong cave at the Pengshui dam site of the Wujiang River, the direction of the karst channel buried some 100 m at depth was found out by means of radio wave penetration method; to look into the leakage that occurred along the batardeau of the upper reaches of the two rivers at Gezhouba dam, self-potential method was used and, as a result, leakage position was accurately located.
Concerning water exploration in Quaternary sediments, two examples are presented which deal with the application of D. C. electrical sounding.
Finally, the paper mentions some problems that are worth noticing in the application of geophysical prospecting to geologic calamity investigation and water exploration.
