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