激光法与比重计法粒径分布相关性试验研究
Experimental study on correlation of particle size distribution by laser and hydrometer method
摘要
Abstract
A series of laboratory tests are performed to establish the correlation of test results from laser and hydrometer method. The characteristics of soil's particle size distribution (PSD) are described by both methods, and the difference between them is explored. The relationships of the sand fraction and the clay fraction between the two methods are discussed quantitatively, and correlation analyses of the size values of d30 , d50 are conducted. A new method is proposed to transform the results of these two methods. Test results show that the PSD curves from laser and hydrometer method are affected by soil properties. The laser method can give a more complete particle size distribution curve. Though the content of sand and clay and the size value of d30, d50 from both methods are different, they can be converted mutually. Furthermore, the results from both methods may be consistent in the ternary diagram with the suggestion by Kerry and Konert et al.关键词
