Through the experiment of outdoor artificial rainfalls.the law of runoff and sediment yield on reshaped slopes during railway construction were studied and compared with that Oil crude slopes.The results indicate 11 construction encampment > road cutting slope > construction shortcut≈crude slope in terms of runoff and 2) road cutting slope > construction shortcut > construction encampment≈crude slope in terms of sediment yield.Besides, factors affecting yield of runoff and sediment on the slopes during railway construction were also investigated,with results showing that 1) runoff on reshaped slopes is mainly affected by gradient of the slope and density of the soil layer on the slope and that moisture saturation of the soil layer on the slope before raining is the key factor deciding the starting time of runoff, and 2) intensify of the soil erosion on the reshaped slope is chiefly influenced by density of the soil on the slope,gradient of the slope and depth of the soil layer disturbed during railway construction.
