摘要
以某预应力箱梁桥研究温度分布对预应力混凝土结构的影响,采用自动远程实时温度采集系统采集现场温度数据,并运用软件ANSYS进行分析。通过监控实测值数据和模拟结果进行比较,可知温度监测系统方便准确,同时结果显示腹板和翼缘板温度变化比其他位置更明显,应力变化也更显著,如何设计和施工必须引起足够的重视。
In order to study the temperature distribution and the corresponding temperature effects on pre-stressed concrete curved box girder bridge,this paper builds and adopts an automatic remote real- time temperature collection system to collect temperature data on site,and further uses the software ANSYS for analysis. By monitoring the measured value data and the simulation results are compared,shows that temperature monitoring system is convenient and accurate,and the results show that the web and flange temperature change is more obvious than that of other locations,stress change is more significant,how to design and construction must cause enough attention.
