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 ,为结构的抗震设计提供设计依据 In the South-to-North Water Diversion Project, the most prominent feature of the Beiming River Aqueduct is that it has a huge water flow and a large body. In the past, there are few studies in this area. Therefore, it is necessary to study the large-scale and heavy load of Yongming River Aqueduct. In this paper, the ANSYS software was used to analyze and compare the modal characteristics of the aqueduct in the four conditions (empty tank, full tank, middle tank over-water, side tank over-water) without isolators and isolators. The seismic design of the structure provides the design basis
