| 摘 要： | 为了充分论证小浪底枢纽孔板泄洪洞充水平压管道的可靠性，对其在上游库水位为252．30m及50m工作水头下的管道振动特性进行了原型观测，通过对原型观测成果的分析研究，得到振动应力在允许值范围内，但振动位移较大的结论，这为今后小浪底水利枢纽孔板洞充水平压管道的改进和安全运用提供了理论依据。

| Abstract: | In order to demonstrate the reliability of the water filling and pressure balance pipeline of flood-releasing tunnel in Xiaolangdi Multi-purpose Project,a prototype observation about the vibration characteristics of the pipeline was done at the upper water level of 252.3m(the working water-head of 50m).After analyzing and researching the results of test,the reasons of the pipe vibration were found out,the results of the test provided the theoretic foundation for the orifice tunnel pressure balance pipe in Xiaolangdi multipurpose dam. |
