介绍了试验研究资料绘在有关函数的坐标纸上仍然不是直线关系的找经验公式简便方法。作为实例,选择了水力学和土力学中常用的关系曲线,分别是点绘在双对数、半对数和普通方格纸上的。借该3例典型曲线叙述了求经验公式的简便方法过程,并求得相应曲线的球体潜水运动阻力系数公式、泥沙沉降速度公式、软土地基沉降固结度公式和给水度公式。
This paper introduces a simple and convenient way to find the empirical formula that the experimental research data is still not in a straight line on the coordinate paper of the function. As an example, the relationship curves commonly used in hydraulics and soil mechanics are chosen, which are plotted on double logarithm, semi-logarithm and normal graph paper respectively. Based on the three typical curves, the simple process of calculating empirical formula is described. The formula of drag coefficient, sediment settling velocity formula, settlement consolidation formula and water supply formula of the corresponding curve are obtained.
