运用大型有限元分析软件ANSYS,对某大桥索塔锚固区在寒潮作用下的力学特性进行分析。结果表明,寒潮作用对塔壁的应力分布产生了不可忽略的影响,故在桥塔的设计中应针对温度裂缝采取一定的防裂措施。
Using the large-scale finite element analysis software ANSYS, the mechanical properties of anchorage zone of a tower pylon under cold spell were analyzed. The results show that the effect of cold wave on the stress distribution of the tower wall can not be neglected. Therefore, certain crack prevention measures should be taken for the temperature cracks in the design of the bridge tower.
