摘要
在5.12汶川大地震中,江油电厂2×330 MW机组和2×300 MW机组主厂房均不同程度受损,如33号机汽机房屋面网架垮塌等,虽未发生人员伤亡事故,但由于修复加固费用高、时间长,电厂发电机组停机时间长,经济损失巨大.为总结经验教训,更好地理解抗震规范条款的内涵,为火力发电厂主厂房结构抗震设计提供参考,本文根据2×330 MW机组和2×300 MW机组主厂房的震害情况,分别进行震害分析.
In the 5.12 Wenchuan earthquake,2×330 MW unit and its main turbine building in Jiangyou Power Plant had been damaged to some extent;for example,roof grid of the turbine of #33 machine collapsed;although there were no personnel casualty accidents.Cost of repairing and reinforcing and time consumption were high.The generator set shut down for a long time,causing huge economic loss.In order to learn from experience,better understand seismic code and provide reference for aseismic design of main turbine buildings in thermal power plants,analysis of seismic damage is made based on damage of 2×330 MW unit and its main turbine building.
