1 试验组次和基本要求鉴于小浪底枢纽工程是一座大型综合利用的水利枢纽,库水位变幅大,根据需求不同,泄水洞群进口高程分别为▽175m,▽195m,▽209m和▽225m四个层次,进口分层布置便于高水高用,低水低用,不仅运用灵活,还有利于解决进水口泥沙淤堵和排漂。同一级水位下要求泄量也不等,在每级水位流量时,采用哪组泄洪运用方式,既能保证安全,又不违背泄洪原则和设计基本要求,这正是本文解决的问题。限于篇幅,本文就
1 Test Group Times and Basic Requirements Given that the Xiaolangdi Multipurpose Dam Project is a large-scale and comprehensive utilization of water conservancy project, the reservoir water level fluctuates greatly. According to different demands, the inlet elevation of the diversion tunnels are respectively ▽ 175m, ▽ 195m, ▽ 209m and ▽ 225m 4 A level, the import of stratification for high water use, low water and low use, not only the use of flexible, but also help solve the siltation sediment inlet and discharge. Under the same water level, the discharge capacity is also not equal. In each level of water flow, it is not the problem that this paper solves. It can not only guarantee the safety but also not violate the principle of flood discharge and the basic design requirements. Due to space limitations, this article
