Effects of seepage-induced erosion on nonlinear hydraulic properties of broken red sandstones

Water inrush hazard is a major threat to safe mining and tunnel construction. During the water inrush process, nonlinear properties of rock mass can change gradually due to the erosion of flowing water. As a special rock mass, red sandstone subjected to water is prone to be disintegrated, resulting in the severe erosion. To study effects of erosion seepage on hydraulic properties of broken red sandstones, a series of seepage-induced particle...
