| Abstract: | By way of an example of analyzing piezometric monitoring data of an earth-rock dam,the application of stepwise regression method to safety monitoring data of earth-rock dams is presented,including the principles,procedures and selection of variables.The result indicates that stepwise regression is an efficient method.The regression solution can indicate the main factors that affect seepage through an earth-rock dam.The calculation result via the regression method is consistent with measured data. |
