某高震区泄洪建筑物上部闸房设计

Design of the Upper Gate House of a Flood Discharge building in A High Seismic Zone

进水塔作为工程咽喉对枢纽抗震安全性影响尤为突出,利用拟静力法对上部闸房进行抗震结构设计是有一定安全裕度的,对重要的进水塔结构有条件应采用动力法计算地震作用效应,以保障工程安全.介绍了某高震区泄洪建筑物上部闸房结构设计,工程施工完毕后工程设防类别提高,相应地震动峰值加速度增加,利用三维整体有限元数值模型的方法进行抗震复核计算,并提出抗震加固方案.

The intake tower,as the engineering throat,has a particularly prominent impact on the seismic safety of the hub.There is a certain safety margin for the seismic structural design of the upper gate house using the pseudo static method.For important intake tower structures,the dynamic method should be used to calculate the seismic effect,in order to ensure engineering safety.This paper introduces the structural design of the upper gate house of a flood discharge building in a high seismic area.After the completion of the project construction,the category of engineering fortification increases,and the corresponding peak ground motion acceleration increases.This paper uses the method of three-dimensional overall finite element numerical model for seismic review calculation and proposes seismic reinforcement plans.
