摘要
针对在役钢管混凝土拱桥的挠度随着环境温度的变化问题,对某已建成的钢管混凝土拱桥,观测了其在同一年冬季相对于夏季挠度的变化情况。同时建立该桥的有限元模型,通过温差的模拟,提取挠度的变化情况。
Aiming at the variation of the deflection of in-service concrete filled steel tubular arch bridge with the ambient temperature,the variation of the concrete filled steel tubular arch bridge winter relative to summer in the same yea has been observed. At the same time,the finite element model of the bridge is established, and the change of deflection is simulated through the simulation of temperature difference.
