摘要
为了精确分析斜拉索加固悬索桥主缆的效果,基于悬链线法针对影响斜拉索索力的因素进行研究。以某管线悬索桥为背景,结合现场量测数据,通过参数化分析,提出影响斜拉索索力变化的主要参数为环境温度和加劲梁处斜拉索锚固位置竖向位移。
To accurately analyse the effect of strengthening suspension bridge by stay cable,study on the influencing factors of cable-force based on catenary method.By parameterization analysis based on field data for a pipeline suspension bridge,it is put forward that environmental temperature and the vertical displacement of anchorage position of stiffening girder for stay cable are main parameters.
