紫坪铺水利枢纽工程引水发电系统震后安全性复核简析
|
摘要
"5.12"汶川地震中,紫坪铺大坝经受住了8级强震考验。本文通过对该工程引水发电系统按照新设防标准下的地震荷载分别进行静态和动态应力分析计算及对计算结果进行分析,提出灾后重建补强或加固方案。希望紫坪铺引水发电系统震后安全性复核的结果,对今后水工发电建筑物的抗震设防有所启示和裨益。
During "5·12" Wenchuan Earthquake,the dam of Zipingpu Water Control Project withstood the Ms8.0 super-strong earthquake.A post-earthquake reinforcement or strengthening scheme is put forward herein in accordance with the static and dynamic stress analyses respectively made on the relevant seismic loading under the new seismic fortification criterion for the water diversion and power generation system of the project and the calculation results from the analyses.It is expected that the result from the post-earthquake safety check for water diversion and power generation system of Zipingpu can provides some references and benefits to the seismic fortification of the similar hydropower structures in the days to come.
