基于瞬变电磁全波理论的截水帷幕渗漏无损检测技术应用及方法验证

Application and method verification of non-destructive testing technology for leakage of waterstop curtain based on transient electromagnetic multiple wave

随着地下工程规模的不断扩大,尤其是深基坑工程的应用增多,地连墙和截水帷幕的稳定性和防渗功能受到密切关注。然而,这些结构常因多种因素出现渗漏问题,威胁工程安全。当前,尽管存在多种检测方法,但尚未有一种既准确可靠又经济高效的渗漏检测手段。文章重点关注瞬变电磁全波技术(以下简称MULTEM技术),通过模型试验和现场实测验证其在地连墙和截水帷幕渗漏检测中的准确性和可靠性。该技术具有高精度、高分辨率特点,有望为地下工程安全施工和质量控制提供新手段,推动相关领域的发展。

With the continuous expansion of the scale of underground construction,especially the application of deep excavations,the stability and seepage prevention function of the diaphragm wall and the water-stop curtain are closely concerned.However,these structures often leak due to various factors,threatening the safety of construction work.At present,although there are a variety of leak detection methods,there is no method that is accurate and reliable while economical and efficient.This paper focuses on the transient electromagnetic multiple wave technology(hereinafter referred to as MULTEM technology),verifies its accuracy and reliability in the leak detection of the diaphragm wall and the water-stop curtain through model tests and on-site measurements.The technology has the characteristics of high precision and high resolution,and is expected to provide a new technique for the safety construction and quality control of underground works,and promote the development of related fields.
