摘　　要：为了充分论证小浪底水利枢纽工程2号孔板泄洪洞的可靠性,对其在上游库水位247.9m左右及100m级工作水头下的孔板段压力特性进行了原型观测分析。原型观测与模型试验和理论分析结果的对比研究,加深了对孔板泄洪洞消能机理及运行特性的认识,为孔板洞在更高库水位下运行提供了参考依据。In order to argue the reliability of the NO.2 orifice tunnel about Xiaolangdi multipurpose dam project, we have done the full scale surveying test ofNO.2 orifice tunnel at the upper water level of 247.9(the working water-head of 100),Then we have analyzed the pressure characteristics of orifice part .Through the above analysis, compared with the model surveying test and theory calculation, we further recognize the principle of energy dissipation and operating characteristics of orifice tunnel,that provide the referent evidence for running at the more high water level.
