最小二乘法在公路土工液塑限试验成果确定中的应用

Put Minimum Quadratic Multiplication into Determining Liquid and Plastic Limits

针对交通规范中采用做图法确定液塑限值而带来诸多不便,采用最小二乘法计算液塑限试验数据,并将其编制成QBASIC程序上机处理,由此确定出的液限、塑限值较传统方法方便、快捷、准确。

Abstract： In view of so many problems caused by traffic standard which using drawing graph to define the liquid and plastic limit, the paper based on the data tested by Minimum Quadratic Multi- plication to calculate liquid limit and plastic one, they are drawn up the QBASIC programme which processed by a computer. The lkluid and plastic limit determined by these methods is conven- ient, quick and accurate than traditional method.
