Analysis on Seepage through Dam Foundation of Fractured Rock Mass

CHAI Junrui[  
It is very important to investigate the seepage through dam foundation of fractured rock mass, which is one of the bases for design of dam construction. The principle of seepage through fracture network for discontinuous media is utilized to analyze the seepage through dam foundation with curtain grouting and drain holes in different combination.
