Comparison and Selection of Flood Discharge and Energy Dissipation Types and Building Shape Design for Longjingwan Reservoir
The selection of flood discharge and energy dissipation types is the main content of flood discharge building design.A reasonable flood discharge plan is the foundation for ensuring the safety and flood control of the entire reservoir hub.In order to ensure that the flood discharge buildings of Longjingwan Reservoir can match the characteristics of open river valleys,mudstone interlayers on the riverbank,and small discharge flow,comprehensive consideration was given to factors such as dam type adaptability,construction conditions,farmland impact,and engineering investment.From the aspects of discharge methods,energy dissipation and erosion prevention types,the layout and structural shape of flood discharge buildings were analyzed and calculated.The demonstration results indicate that the free overflow of the dam spillway combined with bottom flow energy dissipation has good engineering compatibility and flood discharge energy dissipation effect.
