| 摘 要： | 对国内外铁路桥梁设计规范对桥墩横向变位的限值进行比较分析,指出直接套用国外的限值不符合我国的铁路桥梁及车辆现状;然后,根据设计规范计算了墩顶弹性水平位移并转换为相应的梁端折角,分析实际桥墩的横向刚度,最后提出了与“检规”相匹配的桥墩横向刚度设计标准建议值。 |
| 关 键 词： | 铁路桥梁 桥墩 横向刚度 设计标准 检定标准 |

| Abstract: | The different specifications for limited lateral deformation value of piers in several countris' railway bridge design codes were compared,and it was pointed out that the limited value in foreign standard was not suitable for present condition of Chinese railway bridges and trains.Based on the design code,the elastic lateral deformation at pier top was calculated and conversed to the angle at beam end,and the lateral stiffness of real piers were analazed.The suggested design standard of piers' lateral stiffness which matched with that in certified code was given. |
| Keywords: | railway bridge pier lateral stiffness design standard certified standard |
