摘要
为了解决大型渡槽的地震响应问题,从水体的TLD效应出发,通过对渡槽的横断面尺寸调整对比分析,找出水体TLD控制力规律,并在渡槽中沿纵向设全长的隔板,以进一步改善渡槽的横向抗震性能,利用ANSYS软件建立渡槽结构的空间三维动力分析模型。计算结果表明:水体的TLD效应对渡槽的横向地震响应有较大影响;沿槽中纵向增设隔板后,其地震响应进一步减小。
In order to solve the problem of the seismic response of large aqueducts,this article start with the TLD effects of water,adjust the size of cross-sectional dimensions of the aqueduct to contrast and analysis,and to identify the water body TLD control laws.Set the separator along the longitudinal length of the aqueduct to improve the transverse seismic performance of the aqueduct much more,using ANSYS to establish a spatial three-dimensional dynamic model of the aqueduct.The results show that： the water body TLD have a greater impact on transverse seismic effect on the aqueduct;after adding separator along the longitudinal of the aqueduct,its transverse seismic decrease further more.
