摘要
通过对位于高地震烈度山区某座简支T梁桥抗震的复核为例,分析了山区桥梁在地震作用下的受力特点,提出设计应该注意的问题,结合新的公路桥梁抗震设计细则给出了抗震计算方法。
Taking anti-seismic re-check of simply supported T-shape beam bridge of a certain bridge seat in high seismic intensity mountain area as an example,mechanical characteristics of bridge in mountain area under the effect of earthquake are analyzed,and problems that should be paid attention to are proposed.Combined with new seismic design particulars of highway bridge,the anti-seismic calculation methods are proposed.
