收集了高拱坝工程实践资料，论证了构皮滩水电站泄洪消能布置的可行性。构皮滩为双曲拱坝，坝高２３４ｍ，最大泄流量２７４７０ｍ３／ｓ，设６个表孔和７个中孔。表、中孔水舌碰撞，下游设水垫塘消能。通过工程对比，结合模型试验，认为构皮滩水垫塘消能效果好，泄洪消能布置方案是合理的，可行的 Collecting the practical archival data of high arch dam engineering and demonstrating the feasibility of flood discharging energy dissipation of Goupitan hydropower station. Goupitan Beach is a double curvature arch dam with a height of 234m and a maximum discharge capacity of 27,470m3 / s. There are 6 surface holes and 7 mesopores. Table, water hole collision in the hole, the downstream set water cushion pool energy dissipation. Through engineering comparison and model test, it is concluded that the energy dissipation effect of the Goupitan water cushion pond is good and the layout scheme of flood discharge and energy dissipation is reasonable and feasible
