声波测井在坝基水文地质勘察中的应用——以鱼潭水电站工程为例

The application of soundwave logging in hydrogeological investigation of a dam foundation

近年来,声波测井已在工程勘察中广泛开展,其目的主要应用于解决工程地质问题,但对水文地质问题研究应用尚少。作者在鱼潭水电站坝址勘察中,首次应用声波测井资料分析岩体富水条件,论证坝基渗漏及承压水等水文质地问题,本文以此为例,论证了声波测井在水文地质勘察中的应用。

In recent years, the sound wave logging has been widely developed in engineering survey to solve the problems of engineering geology but rarely used in hydrogeological investigation. For the first time, in the survey of dam site of Yutan hydropower plant, the author analysed the existing conditions of the water enrichment in rock mass and proved the possibility of leakage in dam foundation and the distribution rules of artesjon water by using sound wave logging. As an example, this paper describes the application of sound wave logging in hydrogeological survey.
