【摘要】 通过对12座水库不同洪水标准的35组模型试验数据进行统计分析,提出了在控制泄流和自由泄流2 种情况下控制断面水深计算的经验公式法和试验系数法。利用该方法,通过临界水深或单宽流量即可求出控制断面的水深,从而取代了传统的做法,使溢洪道边墙设计更为经济合理。更多还原

【Abstract】 Through statistic analyses of 35 groups of model test data of different flood control standards for 12 reservoirs, empiric formulae and experiment coefficient methods for the calculation of the water level of controlled section under conditions of controlled discharge and free discharge are presented. Using the methods, the water level of controlled section can be calculated through critical water depth and unit flow rate. Thus, the methods can substitute for the traditional methods, and make the design of spillway side wall more rational and economical.更多还原
