汽轮发电机基础抗震性能拟动力试验研究
|
摘要
本文以1251MW汽轮发电机基础为研究对象,设计制作了1:8的试验模型,进行了7度多遇地震与罕遇地震作用下的拟动力试验,研究了基础的地震反应特性。试验结果表明,该基础具有较好的抗震安全储备,即使将设计基准期由50年调整到60年,基础仍能满足抗震设计标准要求。
In this paper,taking a 1251MW steam-turbine generator foundation as an example,pseudo-dynamic tests under intensity 7 frequently and rarely earthquake are carried out after designing and building a 1∶8 scale testing model.And the characteristics of earthquake response are studied.The results indicate that the foundation has preferable seismic capability during the earthquake.Even the design reference period is adjusted from 50 years to 60 years,the foundation meets seismic design codes requirements.
