金安桥水电站坝下游面管道结构与抗震分析研究
|
摘要
混凝土坝下游面钢衬钢筋混凝土管道既是一种新型的布置方式,又是一种新型的结构形式。结合金安桥水电站工程实际,对高地震区混凝土坝下游面钢衬钢筋混凝土管道的结构特性进行了研究,提出了相应的工程措施。研究结果表明,在高地震区采用此种形式的混凝土管道结构上是可行的,只要措施得当,可以确保工程安全。
The Penstock laid on downstream face of dam is not only a new type of arrangement,but also a new kind of structure.In accordance with the practice of Jinanqiao Hydropower Station,the aseismatic characteristics of the penstock laid on downstream face of concrete dam in high earthquake area has been studied and some earthquake-protective measures are put forwards.The research results indicate that adopting the penstock laid on downstream face of concrete dam in high earthquake area is feasible.The engineering safety can be guaranteed as long as the engineering measurements are used properly.
