Soil Liquid Limit and Plastic Limit Treating System Based on Analytic Method

According to two present China national standards, a software as Soil Liquid Limit and Plastic Limit Data Treating System, with analytic method, was developed using object-oriented visual programming tool. The analytic method used in the developed system was different to traditional method of treating soil liquid limit and plastic limit data. N-S algorithm flowchart demonstrated that switch statement and condition statement were taken as main algorithm and second level select nested structure was taken as main frame for the developed system. Three kinds of soil specimens were tested with liquid and plastic limit combined test and the test data was treated with graphic method, Excel software and Soil Liquid Limit and Plastic Limit Data Treating System. The comparative conclusion indicated that Soil Liquid Limit and Plastic Limit Data Treating System improved efficiency and accuracy evidently for treating soil liquid and plastic limit data and had advantages of easy operation and high reliability.
