| 摘 要： | 以中震为切入点,对桥墩地震需求与抗弯能力计算进行了研究,并结合算例进行了分析,结果表明：根据桥墩中震需求能力比确定合理的桥墩截面和配筋率,可以保证大震激励下桥墩核心混凝土不破碎。 |
| 关 键 词： | 桥墩 地震需求 抗弯能力 抗震性能 |

| Abstract: | With the mediate-degree earthquake as the starting point,the thesis studied the earthquake-proof requirement of bridge piers and the calculation of the ability of the anti-bend,and a series of analysis were done combining with specific examples.The result showed that according to the ratio of anti-seismic requirement of bridge piers for the mediate-degree earthquake to determine rational bridge pier section and reinforcement percentage,the core concrete of bridge piers would not be destroyed under the effect of big earthquakes. |
| Keywords: | bridge pier requirement of anti-seismic the ability of anti-bend anti-seismic performance |
