| description | ABSTRACTIn the field of water conservancy engineering, a spillway is a common hydraulic structure that plays a role in flood discharge and dam protection. The selection of the weir surface curve and shape scale of the spillway is significant, and the physical shape of the spillway flip bucket is a critical factor affecting the flood discharge and energy dissipation of the spillway. This paper focuses on a hydraulic model study of the Dashijian Reservoir spillway. The physical shape of the spillway was modified several times during the experiments; the results show that the left and right buckets consist of circular arcs with radii of 13.7 m and 10.01 m, respectively, and the middle bucket consists of a circular arc with radius 11.79 m. The flowing water tongue form is good, the energy dissipation effect is good, and the scouring and deposition form of the downstream riverbed is acceptable. The results of the study can be a valuable guideline for the design of the flip bucket shape of the drainage building. |
