多沙河流水利枢纽动床模型设计研究
Study on Movable-Bed Model Design of Sandy-River Key Water-Control Project
摘要
Abstract
Conventional models for sandy-river key water-control project often fail to accurately simulate actual project operations,resulting in various problems during and after project completion.This paper aimed to enhance the movable-bed model test of sandy-river key water-con-trol project and optimized the design method of the reservoir sediment model.A sandy river reservoir was taken as a prototype,and the pseu-do-scorched sand,chemically stable and moderate weight,was determined as the paramount model sand in the movable-bed model.The pa-per analyzed the similar motion conditions of suspended sand and nudging sand,and consulted relevant experimental results and calculation formulas for sinking speed and sand force with high accuracy.This study identified the scales of water movement,sediment movement and heterogeneous flow movement in the reservoir model,which provided a solid foundation for the validation and formal engineering program tests after the model had been built.关键词
