Excel软件在混凝土施工质量管理中的应用

Application of Excel in Concrete Construction Quality Management

利用质量数据和数理统计方法进行混凝土质量控制、操作、计算均比较繁琐．Excel软件采用交互式窗口操作的特性，可以进行数据统计、绘制数据图形、回归分析、方差分析、线性规划、以及均方值、离差系数等有关数据的计算，都可应用于混凝土质量动态管理，并在实践中获得良好效果．

It is inconvenient carry out the control, operation and calculation of concrete quality by usingquality data and mathematical statistics. Excel, having the characteristics of alternate windows operation,canbe used in the data statistics, maping, regression analysis, variance analysis and linear programming andmacro-order operation. It also can be used in dynamic management of concrete quality, such as drawing qualitymanagement map, calculating mean variance and deviation coefficient, and obtaining the guaranted rate of con-crete intensity. The practices indicate that using Excel in concrete quality management is convenient and effi-clent.
