| Abstract: | In the paper, mean-standard deviation control chart method and mean-covariance control chart method were applied to control dry density of clay filling in No. 24 dam and its accidental fluctuation in construction. By using the method the engineer may earlier put forward forecasting programs and prevent failure. |
