摘要
应用三维有限元程序对某一多跨度石拱桥整体结构进行了动静力仿真分析.研究结果表明,多跨度石拱桥作为一个整体,其自振频率较为密集,桥梁具有足够的安全裕量.计算结果符合实际,可作为其他石拱桥设计时参考.
The three dimensional finite element method is used to simulate dynamic and statical analysis of a muhispan stone arch bridge. The results indicate that the natural frequency of vibration of muhispan stone arch bridge is closely packed and it has adequate safety allowance. The outcome is very beneficial to designing other stone arch bridges.
