The Correlativity Between Compression Coefficient and the Physical Parameters of the Cumulosol in the South District of Kunming |
| |
| Abstract: | From a lot of soil test data,the analysis of correlativity between compression coefficient and the physical parameters of the cumulosol in the south district of Kunming was carried out,and we get mathematical regression formula and the correlation coefficient,which will provide more or less guiding for ascertaining the bearing capacity of foundation soil.It turns out there is a good statistical multiple linear relationship among compressibility coefficient,natural void ratio,liquid limit and plasticity index. |
