摘　　要：系统综述重力坝溢流表孔初步设计,重力坝溢流坝段设计过程中,首先要确定表孔布置格局,选择孔口尺寸、然后确定表孔剖面轮廓,再根据具体情况设计孔口分缝以及闸墩体型。The paper systematically summarizes the preliminary design of the surface spillway of a concrete gravity dam. During the design of the overfl ow section of the gravity dam it is necessary to determine the layout and the size of the spillway fi rst and then the profi le confi guration of the crest outlet, and the arrangement of joints of the outlet and the shape of gate piers should be designed according to the practical conditions.

关 键 词：溢流表孔 孔口尺寸 剖面轮廓 闸墩体型
