摘要
文章以某混凝土斜拉桥为工程背景,分析了体系温差、索梁温差、索塔温差、温度梯度、支座安装温度以及合龙温度等温度效应对混凝土斜拉桥支座受力的影响,研究了支座受力的最不利温度荷载组合,同时对影响支座受力大小的温度效应进行比较并排序,为今后同类型桥梁的支座设计及选用提供参考和依据。
With a concrete cable-stayed bridge as engineering background,this article analyzed the in-fluence of temperature effect on concrete cable-stayed bridge abutment,such as system temperature,temperature difference between cable and beams,cable-tower temperature difference,temperature gradient,abutment installation temperature and closure temperature,studied the most unfavorable tem-perature load combination of abutment force,while it compared and sequenced the temperature effects affecting the abutment force,thereby providing the reference and basis for the abutment design and se-lection of future similar bridges.
