对西班牙塞伦特坝,考虑到坝址时常出现积雪,为避免由于雪崩造成溢洪道的损坏、阻塞或其它问题,因此将溢洪道设计成一个具有渠式泄水隧洞的自流型旁侧溢洪道。至1762米高程的水平基岩面以后,旁侧溢洪道的坡度为0.001,长度为50米,宽为5.5米,右边墙坡度为0.5H/1V,而左边墙则取决于夹角为154°48′的两条直线,其长度 Considering the frequent snow cover at the dam site in Spain, the spillway was designed as a gravity-fed side spillway with drainage tunnels to avoid damage, obstruction or other problems caused by the avalanche. After a horizontal bedrock of 1762 m, the side spillway has a slope of 0.001, a length of 50 m, a width of 5.5 m, a right wall slope of 0.5 H / 1 V and a left wall depending on the angle of 154 ° 48 ’Two straight lines, their length
