Analytic Method for Treating Data of Liquid Limit and Plastic Limit

Analytic method was one of treating the test data of liquid and plastic limit combined test. On the basis of analytic method, a "Liquid Limit and Plastic Limit Data Treating System" was developed using the object-oriented visual programming tool Microsoft Visual C++6.0. Flowchart and pseudo code of liquid and plastic treating procedure corresponding to "JTG E40-2007, cone penetrator 100g" was showed that switch statement and if statement were the main algorithm of treating procedure. Second level select nested structure was taken as main structure frame of treating procedure. In order to test and verify the validity of this treating system. The original data of liquid and plastic limit were received from liquid and plastic limit combined test and the original data was treated with Excel software and liquid limit and plastic limit data treating system. The comparison indicated that liquid limit and plastic limit data treating system improved efficiency and accuracy evidently.
