| Abstract: | A brief introduction was given to the concept of natural tracer method,the characteristics of temperature and conductance distribution in groundwater,and the theory of heat-source method and conductance method for leakage detection.The characteristics of temperature distribution in vertical and horizontal directions and the conductance distribution in horizontal direction in an earth dam were analyzed,and the locations,distribution characteristics,ranges,and leakage rate of main leakage passages of the dam were calculated by use of the virtual heat-source method presented in this paper.The result of study provides a scientific basis for dam leakage control. |
