关于细粒土分类定名的三角坐标图法分析

Analysis of classification and designation of fine grained soil by triangular coordinate graph

三角坐标图法是水利行业进行细粒土分类定名的一种特定方法,它主要采用密度计法的颗粒分析试验结果,并按照砂粒百分含量、粉粒百分含量和黏粒百分含量的不同进行土的分类定名,其中黏粒百分含量是控制指标,其他两个粒组的百分含量是相对指标。根据实际工作总结,通过实际资料数据,分析细粒土采用三角坐标图进行分类定名的规律,达到提高工作效率、减少误差、实现程序化自动化进行分类定名的目的。

Triangular diagram method is to carry on the fine grained soil water conservancy industry classification name a specific method,it mainly USES the densimeter method particle analysis of test results,and according to the sand percentage glue powder percentage and grain percentage of different soil classification name,including clay percentage is a control index,the other two fraction percentage is relative index In this paper,based on the summary of the actual work,through the actual data,analysis of fine grained soil using triangular coordinate map classification and naming rules,to improve the work efficiency,reduce errors,achieve the purpose of automatic classification and naming program.
