摘　　要：溢洪道是泄水建筑物中的重要组成部分,水力与稳定计算是溢洪道设计与安全校核工作中的重要内容。以平塘县黑沟水库为分析对象,对其进行水力及稳定计算。首先,根据工程条件选取合适的溢洪道型式;然后,对其进行堰面曲线计算和泄流能力复核,在此基础上进行溢洪道的水力计算;最后,对溢洪道的稳定性进行计算,主要包括溢流堰和边墙的稳定计算。经方案比选,本工程选用侧槽溢洪道,计算结果表明:溢洪道的泄洪能力满足要求,结构稳定可靠。该研究成果具有重要的实际意义,可为类似工程的设计和安全校核提供参考。Spillway is an important part of the water release structure.Hydraulic and stability calculation is an important part of the design and safety check of Spillway.Taking Heigou Reservoir in Pingtang County as the analysis object,the hydraulic and stability calculation is carried out.First,the appropriate Spillway type is selected according to the engineering conditions;Then,calculate the weir surface curve and recheck the discharge capacity,and on this basis,carry out the hydraulic calculation of the Spillway;Finally,the stability of Spillway is calculated,including the stability of overflow weir and side wall.After scheme comparison and selection,side channel Spillway is selected for this project.The calculation results show that the flood discharge capacity of Spillway meets the requirements,and the structure is stable and reliable.The research results have important practical significance and can provide valuable references for the design and safety verification of similar projects.
