This paper thoroughly demonstrates the water price of South-to-North Water Transfer Project from the viewpoint of economic policies. It is considered that if the project is assigned as a profitable one and built depending on commercial loan from bank completely or mostly, the water price will be too high to be undertaken by users,and if the project places the public good at first while considering the economic benefit, its investment mainly relies on the state (national or local governments) appropriation and self-raised funds and a little from the bank loan on favorable terms, the price determined according to the principle of satisfying the cost and reasonable profit will be relatively lower and can be undertaken by the users in the North China where water shortage is serious. The problem of higher water price of agricultural irrigation to the north of the Yellow River can be tackled by taking measures such as "compensating agriculture by industry" according to foreign practical experiences and relevant suggestions.展开更多

And then,the water will be diverted to Neimongol and Xinjiang Uygur autonomous regions,with transfered annual volume of water 80 billion m\+3. The project possesses great comprehensive benefit. The construction of the project will not only change the appearance of the whole Northwest China, but also open up a wide way for the sustainable development of China in future.展开更多
底栏栅式渠首是新疆粗颗粒山溪性河流引水防沙枢纽的首选类型,但实践运用表明,当引水量超过30 m 3/s时,渠首冲沙有利、工程布置紧凑的优势逐渐丧失,后期运行管理效益大打折扣。为此在保留原有布置优势的情况下,以扩大底栏栅引水流量为目...底栏栅式渠首是新疆粗颗粒山溪性河流引水防沙枢纽的首选类型,但实践运用表明,当引水量超过30 m 3/s时,渠首冲沙有利、工程布置紧凑的优势逐渐丧失,后期运行管理效益大打折扣。为此在保留原有布置优势的情况下,以扩大底栏栅引水流量为目标,提出了“⊥”型廊道新结构及优化布置方案,新结构在原垂直水流方向“—”型廊道结构基础上增设了顺水流方向“|”型廊道(根据流量的大小可布置双排甚至多排“|”型廊道),并结合底栏栅水流动力方程及取水流量计算方法得到了“⊥”型廊道取水流量的计算方法。随后以新疆头屯河渠首为例,在保持原平面布置不变的情况下引入“⊥”型廊道新结构,其引水量可达48.96 m 3/s,提升了39.89%,工程造价降低了63.46%。“⊥”型廊道新结构及布置方案突破了传统底栏栅式渠首设计引水流量相对较小的限制,拓宽了底栏栅式渠首的适用范围,还提高了经济效益,可为此类工程提供新的工程方案。展开更多
