黄河小浪底枢纽泥沙问题的试验研究

Study on sedimentation of Xiaolangdi project on the Yellow River

本文利用小浪底枢纽多年模型试验资料，总结了黄河小浪底枢纽泄水建筑物进口弯道凹岸侧向进水口前的河势流态、水流结构、含沙量分布、异重流、淤积地形及漏斗形态等特点，提出了泄水建筑物进口布置及运用的原则．

Based on the data obtained from the physical model with suspended load of the Xiaolangdi project which has special layout of outlet facilities,the behaviors of flow structure,sediment concentration distribution,density current,deposited topography and tunnel-shape morphology in front of these outlets are summarized and the principles of design and operation of the outlet facilities are suggested in this paper.
