Locating the plane concentrated seepage in dam by transient temperature field

摘要：

1D transient detection model for the plane concentrated seepage as the heat boundary mainly in the soil body whose diathermancy is poor is established. The temperature characteristic in the soil of the dam is numerically simulated. The space location is parameterized and the objective function is setup. The time and other parameters denoting space location of the concentrated seepage are estimated by temperature regression via the data extracted from the numerical simulation of dam, and then the goal to detect the location of the concentrated seepage is reached. The precision of the location parameters are higher and that of time is poor.
