摘要
依据GB 50111-06铁路工程抗震设计规范和青藏铁路9度地震区安评报告,运用MIDAS结构分析程序对既有乌达特大桥门式墩进行了简要分析对比,检查了原有结构的抗震安全性及系梁对于结构工作的影响,结果表明该桥门式墩设计是安全可靠的。
According to ＂earthquake-proof design norm of railway project＂ （GB 50111-06） and ＂safety evaluation report of the seismic area of 9 degree of Qing-Zang railway＂, it makes a brief analysis of the portal pier of Wuda super large Bridge with MIDAS structure analyzing program and checks the earthquake-proof ability of the original structure and the influence of tied girder to structure. The result shows portal pier design of this bridge is safe and reliable.
