土壤颗粒分析密度计法计算的研究

土工试验中密度计当计算工作量是很大的。本文提出了的方法是根据司笃克公式和诺模图的理论，事先绘制土壤料戏及含量百分数的有关曲线族，以后只要根据相关测验数据，直接在图纸上确定各测点益，从而根本取消繁杂的计算工作并保证精确度。

STUDY ON CALCULATION BY DENSITY CALCULAS IN SOIL GRAIN ANALYSIS

The amount of calculating work by using density calculas in soil test is very large. In the case of method proposed in this paper, on the basis if Stokes formula and theory of nomographic chart, previously drawing related curve family of soil size and percentage by content, consequently, according to relative test data, we can determine, with accuracy, the position of surrey points on the drawing paper derectly, thus thoroughly cancelling complicated calculations.
