中文摘要:
      防渗墙工程是地下隐蔽工程,其施工质量和运行性状直接影响水库大坝安全和效益的发挥,为评估防渗墙的施工质量和工作性状,实现预期的防渗效果和使用寿命,需要对防渗墙进行有效监测。本文总结了国内深厚覆盖层防渗墙监测技术进展,对深厚覆盖层防渗墙监测设计原则、监测仪器选用和布设要点、难点,监测结果分析方法和考虑因素进行了分析,并给出了进一步提高仪器成活率和监测精度的对策建议,对深厚覆盖层防渗墙更好地进行安全监测具有参考价值。
英文摘要:
      The cut-off wall project is an underground concealed project. Its construction quality and operation characteristics directly affect the safety and benefits of the reservoir dam. In order to evaluate the construction quality and working characteristics of the cut-off wall and realize the expected anti-seepage effect and service life, it is necessary to effectively monitor the cut-off wall. This paper summarizes the progress of monitoring technology of cut-off wall in deep overburden in China, analyzes the monitoring design principles, key points and difficulties of monitoring instrument selection and layout, monitoring result analysis methods and considerations, and gives countermeasures and suggestions to further improve the survival rate and monitoring accuracy of instruments, It has reference value for better safety monitoring of cut-off wall in deep overburden.
