Research on Detecting Multi-Passage Leakage in Dam by Temperature in Bores

Abstract:

Multi-passage leakage often occurs in earth-dams, the locations of all seepage passages must be located actually to repair the dams absolutely. Fluxs and temperatures of water in passage and in pore of soil are different, so the special temperature distribution of this kind of dam is formed by heat transfer. Locations of concentrated leakage passages are assumed known. Analysis formula for temperature field of the dam with multi-passage leakage is established by that of the dam with single leakage passage. Coordinate is transformed by model of Bursa–Wolf with six parameters. Finally, the mathematic model for detecting multi-passage concentrated leapage in dam by temperature is put forward. In case, plane model for detecting column passage is established by simplifying conditions.
