摘　　要：针对公路与水电土工试验规程中所采用的作图法确定液塑限值而带来的诸多不便,采用数学解析法、最小二乘法、回归分析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。同时对公路与水电土工试验规程中所采用的不同圆锥下沉深度而计算出的液塑限值进行了比较。In view of the inconvenience of diagrammatic method adopted for determining the liquid and plastic limits stipulated in the experimental regulations for highway, hydropower, and geotechnical engineering, we present the analytic method, least square method and regression analysis method in the form of QBASIC programme processed by computers. The result by the analytic method is more accurate and the implementation of it is more convenient comparing with those of the diagrammatic method.
