摘　　要：随着大量直河段水利水电枢纽的修建,有压接无压泄洪洞的应用日益广泛,而目前国内外并无有压接无压泄洪洞设计的系统介绍。本文总结了多年有压接无压泄洪洞设计的工作经验,并收集整理国内已建、在建工程有压接无压泄洪洞特征参数,提出了有压接无压泄洪洞设计的系统思路和设计方法。With construction of many hydropower stations on straight river,more and more spillway tunnels with free flow section in connection with pressure flow section are becoming popular. However there is no systematic indroduction to such spillway tunnels both in China and abroad. In this paper the writers summarizes their own experiences for many years in this field and presents the systematic thought and design method for spillway tunnels of free flow section in connection with pressure flow section, which gives other designers a reference in the future.
