液限塑限的联合试验是公路工程设计、科研和施工中最基本的常规试验之一,正确确定液限塑限具有重要的实际意义。然而在实践中我们感到液限塑限联合试验的计算及制图既烦琐又费时,而且用手工制图,查图精度较低,容易产生比较大的误差。为此,我们用BASIC语言编制了计算及制图程序,可以在IBM及兼客微型计算机上运行,程序运行过程中的文字输出均为汉字,使同时只需输入原始试验数据,整个计算及制图在几 The combined test of liquid limit and plastic limit is one of the most basic routine tests in highway engineering design, research and construction. It is of important practical significance to correctly determine the liquid limit and plastic limit. However, in practice, we feel that it is cumbersome and time-consuming to calculate and map the liquid-limit combined test. Moreover, the precision of hand-drawing and check-list is low and large errors easily occur. To this end, we have compiled the calculation and drawing program in BASIC language, which can run on IBM and concurrent client computers. The text output during the program running is Chinese characters, so that only the original test data can be input at the same time. The entire calculation and drawing a few
