The mesh cage piled up retaining walls and laid slope protection, in which the filling is loose and more pores, will be convenient to filling and pore water discharge in the downslope soil. Once infiltration in soil, can use masonry faster to discharge, reduce the water table, thereby reduce pressure of wall and downslope groundwater . . Gabion structures is used in landslide and debris flow control works, water discharged in time, reduce the risk of wall damage, while the good deformation capacity of retaining wall can effectively buffer the impact of unexpected external forces.
