通过模型试验 ,对甘肃省金昌市引硫济金枢纽工程的泄洪冲沙闸和溢流坝下游消能防冲效果、引水防沙效果及引水隧洞进口段水流流态进行了试验和研究。并以此为依据 ,为设计部门提供了合理的意见和建议 ;在此基础上 ,通过对枢纽工程运用后期进水闸前水流、泥沙的运动特性进行分析和研究 ,运用“分离流区 ,束水攻沙”的原理解决了引硫济金枢纽工程的引水防沙问题 Through the model test, the energy dissipation and anti-scouring effect, the effect of water diversion and sand control, and the water flow pattern at the inlet of the diversion tunnel were tested and studied for the flood discharge sluice gates and the downstream overflow spillway of the Sulfur-Diversion Project in Jinchang City, Gansu Province. On this basis, through the analysis and study on the movement characteristics of water flow and sediment before the sluice in the late stage of the project, the “separation flow area, beam Water attack sand ”principle solves the sulfur diversion of economic and sediment water diversion and sand control issues
