摘　　要：马家山水库取土场位于山坡侧,受林地界限影响,土场空间位置狭窄,且取土层高度57 m左右,下部面积约4750 m^(2),上部面积约567 m^(2),现场受地形限制不具备修筑上至顶部道路。根据实际情况并结合以往经验,制定了分区、分层,自上而下、逐次倒运的取土方式,确保了机械及作业人员的安全。Majiashan Reservoir soil extraction field is located on the slope side,affected by the boundary of forest land,the spatial position of the soil field is narrow,and the height of the soil extraction layer is about 57 m,the lower area is about 4750 m^(2),and the upper area is about 567 m^(2).Due to terrain limitations,it is not possible to build a road leading to the mountaintop on site.According to the actual situation and combined with previous experience,the soil extraction method of zoning,layering,top-down and successive reverse transportation has been formulated to ensure the safety of machinery and operators.
