摘要

对于山区桥梁来说,由于地形的限制,桥梁一般位于平、竖曲线上。这种桥梁的地震响应有着其自身的特点。梁桥仍然是公路建设的主要桥型。用自编的梁桥地震响应分析程序,对此类桥梁进行了计算和分析,总结了此类桥梁的地震响应特点,提出了抗震设计的一些建议。
The bridges located in mountain area are built on plane curve and vertical curve for the limited of landform,in general.The response of these bridges has its unique characteristics.Girder Bridge is still the main type of bridges in highway construction now.In this paper,program for earthquake response analysis of Girder Bridge is established,and a bridge on plane curve calculated and analyzed is with that program.Through that,some characteristics is generalized and some suggestion for earthquake-resistance is put forward for girder bridge on plane curve through of a bridge.
