| 摘 要： | 研究目的:通过研究在制动力作用下墩顶刚度的提高程度,验证现行设计规范的合理性。研究结果:测试数据表明在制动力作用下墩身纵向刚度提高较小,提高幅度小于3%。对于常用墩台基础可不考虑制动力作用下墩顶刚度的提高影响,按现行铁路规范中的方法计算墩顶刚度能够满足当前工程需要。

| Abstract: | Research purposes:This project verifies rationality of current standard for design by researching the increased degree in longitudinal horizontal stiffness of railway pier under braking force. Research results:According to the measured data,the increased range of stiffness of bridge pier is less than 3%.The increase of stiffness of bridge pier under braking force can be left out of account on common pier and abutment foundation.The stiffness of bridge pier which be calculated according to current standard for design can meet the current requirement of railway engineering. |
