渗漏是水工建筑中最为常见的老化病害之一,准确快捷的查找到渗漏源及渗漏通道是解决渗漏问题的关键环节。该文以某水库大坝为例,针对多年来左坝渗漏存在的问题,应用了水化学分析以及一系列基于示踪技术的手段,确定了左坝廊道内异常涌水的渗漏源。示踪连通试验相互印证、互为补充确定了渗漏途径为坝体渗漏。该文采用多种方法综合应用,为以后水库渗漏勘察提供新的视角,为多学科在水库勘察中的结合与交叉应用提供了案例。
Leakage is one of the most common aging diseases in hydraulic construction. It is a key link to find out the leakage source and leakage channel accurately and quickly. In this paper, taking a reservoir dam as an example, aiming at the problems existing in the left dam leakage over the years, a series of techniques based on tracing techniques and water chemistry analysis were applied to determine the source of abnormal gushing in the left dam gallery. Tracer connectivity test confirmed each other to complement each other to determine the leakage path for the dam leakage. This article uses a variety of methods integrated application, providing a new perspective for future reservoir seepage investigation, providing a case for the combination and cross-application of multidisciplinary investigation in reservoirs.
