摘要： 堤防防渗墙在抵御洪水，保障生命财产安全方面发挥着重大作用。针对堤防防渗墙完整性检测问题，提出一种基于高密度面波法的快速检测方法。首先介绍了高密度面波法的基本原理、检测方法和数据分析方法。接着，在此基础上为提高检测效率，开发了牵引车拖曳、自动激发装置集成的快速数据采集系统。并利用不同场地试验验证了该系统及方法的效率，结果表明拖曳式高密度面波技术的快速检测系统的效率高于传统插针方式，且效率为传统插针方式的3-4倍。

Abstract: The cut-off wall in levees play an important role in resisting floods and protecting the safety of human been and properties. A high-density surface wave method for the rapid detection of the integrity of the cutoff wall in levees is developed. The principles of the high-density surface wave method, integrity testing methods and data collections are first introduced. To improve the efficiency of the detection work, the vehicle mounted device with automatic triggering and automatic data collection systems. This device was tested and verified at various project locations. The results indicate that this method is an efficient integrity test system and is three to four times as fast as the conventional integrity testing devices.
