Minghe aqueduct modal analysis of structures

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.
