摘要
在青藏铁路九度地震区简支梁桥抗震设计中,采用了地震力简化公式“回归法”进行抗震设计。在“回归法”计算中,分析了恒载及活载、桥墩、基础和基础土对墩底地震力影响,并进行了修正。
In the design of railway bridge with free-supported beam in nine-degree seismic regions of the Qinghai-Tibet Railway,a regression analysis of earthquake forces with simplified formula is made. All elements in the regression analysis that affect the calculation of earthquake forces against a bridge pier are discussed.
