摘要
应用统计控制图法,选用平均值———标准差、平均值———极差控制图法,控制24#坝粘土填筑干密度值及施工偶然异常波动,早期提出警报,以保证土坝的施工质量。
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.
