Abstract Research is made on the fractal features of fault gouges at Laxiwa hydropower station. The fault gauges are of the same fractal dimension when the fault gouges are of the same ingredients. Fault gouges are of apparent fractal feature. There is clear correlation between fractal dimension and mechanical parameter. It is a convenient to decide the mechanical parameter of weak interlayer by using this correlation.
