| Abstract: | A large digital high pressure apparatus for measuring the permeability coefficient and seepage deformation is developed,which consists of the mainframe,servo loading system,measuring system and data acquisition system.Using the apparatus,the permeability coefficient and seepage deformation tests could be done for the rock-fill materials whose maximum particle diameter is 200 mm and gravels covered over dam base.The technical parameter,the design idea and the solution for technical difficulties are described particularly.For this apparatus,the maximum vertical stress is 6 MPa,the maximum head pressure is 1.6 MPa,at the same time,it has the capabilities of automatic collection,real-time graphics and so on. |
