摘要
多沙河流取水口泥沙淤积问题一直困扰着引水枢纽工程的安全运行。以我国西北地区某火电厂引水工程为例,针对导流墙体型参数对取水口前冲沙效果的影响,进行了水工实体模型试验研究。试验研究过程中采用了潜没式、露顶式以及复合式3种不同型式的导流墙,观测了不同型式导流墙在多种流量下的冲沙效果,在理论分析的基础上,提出了关于取水口防沙方面的导流墙体型选择建议。
The sediment deposition in water intake on sediment - laden rivers affects the safety operation of water diversion project. Taking the water diversion project of a thermal power plant in northwest region of China as an example, the hydraulic physical model experiment was carried out to study the influence of body shape parameters of guide wall on sediment flushing effect in front of the water intake. Three shapes of guide walls were used in this experiment, namely the submersion type, top - exposed type and compound type. The sand flushing effect of different shapes of guide walls under different flow rate was observed and tested. By combing with the theoretical analysis, some suggestions on the guild wall shape selection were put forward to prevent the sediment deposition in water intake.
