Abstract: Leakage is common for reservoir dams which not only affects the project benefits, but also causes serious hidden risks, can even lead to a dam break. Locating the leakage and its passage is the basis for further treatment which is key to ensure the safe operation of reservoir dams. At present, there are many leakage detection methods with their own applicability and limitations, and are restricted by site condition, environmental condition and geological conditions. Suitable methods should be selected based on method characteristics and site conditions, to achieve better detection effect.

Key words: reservoir dams, leakage defect, detection methods

摘要： 水库大坝渗漏病害十分常见，不仅影响工程效益，而且给水库大坝安全运行造成严重隐患，甚至导致溃坝事故。查明渗漏位置及通道是治理渗漏病害的前提与基础，据此才能根治渗漏病害，确保水库大坝安全运行，因此，水库大坝渗漏探测工作十分重要。当前，水库大坝渗漏探测方法众多，但均有其适用性和局限性，并受到场地条件、环境条件、地质条件等制约，应根据方法特点和现场条件选择适用的方法，以达到较好的探测效果。
