【摘要】 应用铁路抗震规范中介绍的方法和"m法"对一座连续箱梁进行了建模计算分析,通过地震反应结果的对比分析,得出两种方法结果的差异度。"m法"在我国铁路桥梁中的应用还不多见,研究结果丰富了铁路桥梁考虑桩-土相互作用的桩基模拟理论。可以为铁路桥梁在设计过程中的建模分析提供参考。更多还原

【Abstract】 Some models of long span continuous girder is established by using the method of Standard for seismic design of Railway bridges and the "m-method",the seismic responses of long span continuous girder is calculated.The degree of difference of two methods can be found by analysis of the results.The "m-method" is rarely used in China’s railway bridge;it can be used to simulate the pile.And give some advice for establishing model of the bridge.更多还原
