[摘要]  武漢火車站的列車將從站房中高速穿過，通過車輛-等效橋梁耦合系統(tǒng)以及橋梁-站房系統(tǒng)的分步求解，確定了車輛-橋梁-站房結(jié)構(gòu)系統(tǒng)動(dòng)力學(xué)計(jì)算的求解策略與方法，研究了列車高速通過站房所引起的建筑結(jié)構(gòu)動(dòng)力響應(yīng)以及相應(yīng)的理論和方法。并針對(duì)所得結(jié)果選擇了合適的評(píng)判標(biāo)準(zhǔn)，解決了在高速列車穿越引起的振動(dòng)下建筑結(jié)構(gòu)的安全、經(jīng)濟(jì)及使用性能的問題。

Abstract:  The dynamic responses of train-bridge-station system has not been studied while train will go through Wuhan railway station with high speed. By solving the train-equivalent bridge system and bridge-station system, the principle and methods of dynamic responses of train-bridge-station system are pmvided. The dynamic responses of station due to the crossing of high speed train are studied. The results are evaluated with appropriate criterion. The safety, economy and performance due to the crossing of train are settled．
Keywords:  vehicle-bridge-station system; dynamic responses; vibration serviceability
