| 摘 要： | 依据相关规范对制动力按最不利影响取值,根据Newmark-β数值积分方法编制程序,计算在列车制动力作用下多跨简支梁结构在不同影响参数（如制动速度、墩台刚度）下的纵向动力响应,以判断结构是否满足高速铁路运营的安全性要求。

| Abstract: | Taking braking force value as the most adverse conditions,the software is programed according to Newmark-β to calculate the longitudinal response of the multi-span simply-supported beam bridge under braking force at different speeds and pier stiffnesses.Based on it,it can be estimated that whether the structure meets the safety requirement of high-speed railway. |
