土的液塑限联合试验的计算及制图,较为麻烦,尤其是在没有双对数座标纸的情况下。同时,因手工制图、查图的不精确,容易给试验结果带来误差。为方便起见,这里提供一个BASIC程序,可直接在PC-1500袖珍机上运行,使用起来,不仅迅速(一般用时半分钟左右),且由于土的液限、对应塑限时的锥入深度和塑限均用代数方法求得,从而避免了因手工绘图、查图带来的精度误差。
Computation and mapping of soil-plastic-plastic joint test are troublesome, especially in the absence of double logarithmic coordinate paper. At the same time, due to the hand-drawing, the inaccuracy of the chart, it is easy to bring errors to the test results. For convenience, here is a BASIC program, which can be run directly on the PC-1500 compact machine. It is not only fast (usually takes about half a minute), but also due to the liquid limit of the soil, corresponding to the depth of penetration and plastic limit Are obtained by algebraic method, thus avoiding the error caused by manual drawing, check the accuracy of the map.
