摘要
斜槽作为排洪系统进水构筑物,被广泛应用于汇水面积较小的尾矿库。在低水头情况下,选择平盖板斜槽能大大提高进水能力,可有效解决调洪水深较小的小尾矿库的排洪问题。在斜槽—管(或隧洞)式排洪系统设计时,应充分考虑斜槽盖板类型、斜槽坡度、水头及泄流流态对整套系统泄流能力的影响。对斜槽式排洪系统的泄流能力进行了实例探讨,推荐采用平盖板斜槽式排洪系统。
Chute has been widely used as intake structure in the tailings pond with small catchment area. When the water head is low ,a chute with flat plate is selected to enlarge its flow capacity ,which can solve the flood drainage problem in the tailings pond with low water head. The influence of chute plate type, chute slope, water head and flow states on flow capacity should be considered adequately in the design of chute-culvert（ or tunnel）flood drainage system. A case is given to discuss the capacity of the chute flood drainage system. Flat chute-culvert flood drainage system is recommended.
