Multiparameter technology on dam leakage

Abstract

Leakage is one of the most important hidden dangers that will affect the safety of the dam's operation. The method of using the nature tracer, such as temperature, conductance, can be used to detect the leakage passage on dam. One parameter will easily bring on the wrong result or the result shows parts of the whole problem. The multiparameter technology has been used to monitor the safety of the dam and has achieved great success but in leakage passage detecting is rarely used. The multiparameter detecting technology which synthesizes the advantage of the nature tracer, manpower tracer and isotope has gained great effect on detecting the leakage passage of dam.© 2008 Science Press Beijing and Springer-Verlag GmbH Berlin Heidelberg Geotechnical Engineering for Disaster Mitigation and Rehabilitation.
