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.
