摘要
矮塔斜拉桥采用悬臂施工法浇筑过程中,0#块空间受力情况十分复杂.以某矮塔斜拉桥为工程背景,通过ANSYS有限元分析软件,根据圣维南定理,对该桥的0#块进行有限元模拟,并将其分析结果与现场监测数据进行对比.研究结果表明采用有限元分析方法可以较为真实的模拟0#块空间受力情况,且在最不利荷载工况下,0#块整体以受压为主,压应力值满足设计和规范要求.
When the cantilever construction method is used in the construction of the extradosed cable-stayed bridge,the stress of 0# block is very complicated. Based on an extradosed cable-stayed bridge and Saint Venant principle,a finite element simulation is carried out on the 0 # block through the finite element analysis software ANSYS. At the same time,the results of finite element analysis are compared with field monitoring data. The research results show that the finite element analysis method can realistically represent the spatial force of 0 #block. Under the most unfavorable load condition,the main stress of 0 # block is pressure,and the pressure meets the design and specification requirements.
