Certain permeability capacity exists in red beds rock due to the structural plane, weathering fracture and other fractures exist in red beds rock, which causes permeability happen to dam foundation rock and then led to problems of reservoir water loss and decrease of stability of rock and benefits etc. Permeability of dam foundation rock is one of the common engineering geological problems in red beds water conservancy and hydropower engineering. Main geological controlling factors have been confirmed through the analysis of forming process mechanism of permeability problems of red beds dam foundation etc., permeability features of rock, permeability features and laws of different lithological combinations and corresponding geological basis and analysis methods have been provided for the design of anti-permeability for hydraulic dam.
