摘　　要：探讨了穿越大型河流热水供热管道的设计计算,涉及直埋无补偿冷安装管段的安定性分析、竖井及顶管管段的补偿验算、直埋弯头的强度验算。The design calculation of hot-water heat-supply pipeline crossing large river is discussed. The calculation involves the stability analysis of directly buried pipe section with cold installation without ex- pansion joint, the compensation checking in shaft and pipe jacking section and the strength checking of di- rectly buried elbow.

关 键 词：热水供热管道 穿越河流 顶管 直埋无补偿 直埋弯头
