Penetrating properties of non-Darcy flow in fragmentized rocks |
| |
| Abstract: | A patented device has been designed for the purpose of penetrating properties measurement. By the aid of MTS815.02 Rock Mechanics Test System, the device can measure the penetrating properties of fragmentized rocks by transient or steady percolating method. In the article, the configuration of the device is described. The test technique and its strongpoints are introduced. The relation between the penetrating properties and the load as well as the grain diameter is obtained by linear regression analysis. This test technique is of practical importance in mining, civil engineering, irrigation works and traffic engineering, and hence it will certainly come into broad uses. |
