中文摘要:
      面板坝建设常出现大坝渗漏、面板破坏、结构性裂缝、止水失效等问题,其中大坝渗漏是面板坝最突出问题之一。因面板坝防渗体位于坝体上游面,渗漏检测面临漏点分散、深水等难题。为提高面板坝渗漏检测效率,提出一种集声纳查漏、水下机器人高清摄像及喷墨示踪、连通性试验及水化学分析等多种手段融合的视声一体化渗漏探测技术,该检测技术在蓼叶水库渗漏检测中的成功应用,可为类似面板坝渗漏检测提供借鉴。
英文摘要:
      Concrete face rockfill dam construction always appears problems, such as leakage, concrete panel damage, structural crack, and water stop failure, etc. Among them, the dam leakage is one of the most prominent problems. Due to the impervious body located in the dam upstream face, the leakage detection is faced with problems of scattered points and deep water. In order to improve the efficiency of dam leakage detection, this paper presents a video-sonar integrated leakage detection technology, which integrates sonar leakage detection, high definition camera and ink-jet tracing with ROV, connectivity test and hydrochemical analysis. The detection technology is successfully applied to the leakage detection of the Liaoye reservoir, which provides reference for the leakage detection of concrete faced dams.
