摘要
采用有限单元法,对某电站坝后式厂房引水系统进行了静动力承载特性研究,从而确定了坝后背管的布置形式、结构形式、厂坝分缝处过缝措施等。对引水系统正常运行和抗震安全性进行了评价,并确定相应的工程措施,以供相似工程参考。
The static and seismic behaviors of the water diversion system in a behind-dam powerhouse are analyzed . Then, the layout, structural form and engineering measures to cross the joints between the dam and powerhouse for the steel penstock are determined .Moreover , the safety of the water diversion system under the normal operation and earth-quake conditions are evaluated .Some engineering measures are proposed .It could be a useful reference for similar pro-jects.
