本文以在槽墩与上部结构之间设置了叠层橡支座的梁式渡槽为对象，采用非线性时程分析法，研究了３种支承方案的水平地震作用．结果表明，设置橡胶支座对渡槽结构的地震响应有明显的控制作用，对渡槽设计有一定的参考价值．
In this paper, a beam-type aqueduct with laminated rubber bearings is set up between the slot pier and the superstructure. The nonlinear seismic analysis method is used to study the horizontal seismic action of the three bearing schemes. The results show that the rubber bearing is obviously effective in controlling the seismic response of the aqueduct and has some reference value for the aqueduct design.
