【摘要】 防渗墙在水利水电工程中是被广泛采用的一种基础防渗处理形式,是一项重要隐蔽工程。针对防渗墙施工后期的质量检测,业界做了大量研究,其中对防渗墙体几何尺寸参数的无损检测是防渗墙质量检测重要内容之一。利用防渗墙体与周围介质存在着电性、力学性质的差异,通过大量现场试验与分析研究,总结出一套适用的综合无损检测方法,实现了对防渗墙体几何尺寸中厚度、深度等参数的检测,在实际应用中取得较好成果。更多还原

【Abstract】 The leakage-proof wall is a kind of anti-leakage method to foundation adopted widely in the field of constructing the Water Conservancy and water power plant and it is a significant concealed project.Aiming at the quality detection of the leakage-proof wall during the later course of construction,those in the relevant vocation carried out a great deal of work and the nondestructive flaw detection to the geometrical parameter of the leakage-proof wall is one of the most important item in it’s quality detection.Utilizing the electrical-magnetic and dynamic difference among the underground medium,the authors summarized a set of suitable synthesize of the nondestructive flaw detection by a large number of on-the-spot test and analyse,then actualized the aim of inspection detection to the geometrical parameter of the leakage-proof wall and got better result in the practical application.更多还原
