- 程序介绍 ( Program Introduction)
To identify grain size characteristics of soils, grain size distribution curve is developed. First, sieve analysis is conducted. A variety of sieves with different openings are stacked, with the largest opening sieve on the top and smaller on the lower sections. When a relatively large percent passing through the sieve with 0.075mm opening (e.g., more than 10% as a guideline) is obtained from the sieve analysis, a hydrometer analysis is conducted.
This program process the raw data from sieve analysis and hydrometer analysis to get the grain size distribution curve and other parameters like D10, D30, D50, D60, Cu and Cc.
D10: effective grain size, the diameter of the soil particles for which 10% of the particles are finer.
D30: the diameter of the soil particles for which 30% of the particles are finer.
D50: mean grain size, the diameter of the soil particles for which 50% of the particles are finer.
D60: the diameter of the soil particles for which 60% of the particles are finer.
Cu: coefficient of uniformity, defined as Cu = D60/D10.
Cc: coefficient of curvature (other terms used are the coefficient of gradation and the coefficient of concavity) defined as Cc = D30*D30/ D60/ D10 .
The coefficient of uniformity and the coefficient of gradation affect the soil packing arrangement.
