and field test method. First, the permeability tensor of the fractured rock mass was determined preliminarily using the fissure sample measuring method to obtain the principle values and directions, and then it was modified using the field test method. The permeability tensor of fractured rock mass in dam foundation of some southwest hydropower station was calculated with the above method. Through......
