Abstract The tests for permeability of rock-like sample with filling fractures under high confining pressure and hydraulic pressure are carried out. Based on the ratio test，the specimens simulating sandstone are made；and the tests are made by self-developed triaxial instrumentation. From the results，it is found that：(1) The permeability coefficients of different filling fractures specimens are different；but they are always in the same magnitude under different confining pressures. (2) The permeability coefficient shows downward trend with the increase of confining pressure. (3) The geometrical characteristic of permeability structural surface is one of main factors influencing permeability of sample；(4) Permeability law of sample should be based on the test results.

Key words： rock mechanics filling joint similar material permeability
