洺河渡槽隔震结构模态分析

Minghe aqueduct modal analysis of structures

在南水北调工程中 ,氵名河渡槽的最大特点是输水流量巨大、体型庞大。而以往在这方面的研究却很少。因此 ,对体型庞大、荷载巨大的氵名河渡槽进行研究非常必要。本文利用ANSYS软件 ,对渡槽在不设隔震器和设置隔震器时的 4种工况 (空槽、满槽、中槽过水、边槽过水 )的模态特性进行分析比较 。

In South-to-North Water Transfer Project , Minghe Aqueduct's most characteristics are large discharge and great size.Such studies in this aspect in past is rare.Therefore,it is important to study this aqueduct.Under different states of the isolated set and without isolated set,the modal was analyzed and compared by using ANSYS in this paper about four states (aqueduct without water, aqueduct with water in three troughs, aqueduct with water in the middle trough, aqueduct with water in side troughs),which provides the seismic design theory and evidence for engineering practice.
