| Abstract: | Seepage of hydropower projects often haunts the normal operation of the projects.Regarding the seepage with mud from the stilling basin of the flood gate of one hydropower station, in this paper, analysis and study through the general tracer technology such as isotope tracer method, temperature of the tracer method, conductance tracer method, velocity measurement and connectivity tests are performed.Seepage causes, position and mud resources from the drainage pipeline of the stilling basin foundation are investigated clearly.Impacts on the seepage stability of the structural foundation are determined.This provides basis to the engineering measure to be taken. |
