喀兰古连续箱梁桥温度应力监控与有限元分析

Kalangu continuous beam bridge temperature stress monitoring and finite element analysis

采用预埋的振弦传感器对喀兰古连续箱梁桥在施工过程中的箱梁温度场进行了现场实测。利用ANSYS有限元软件建立该桥0#段有限元模型,对该结构在施工阶段的温度应力进行了模拟计算,并与实测应力进行对比分析,得到喀兰古连续箱梁桥在施工阶段的温度应力分布规律,并提出了设计和施工方面防止过大温度应力的建议。

Temperature field in Kalangu continuous beam bridge has been measured with the embedded sensors. Combined with finite element software ANSYS to establish the 0# section finite element model, we study the concrete continuous girder bridge construction stress control method, and optimize the high temperature difference areas of the continuous girder bridge construction monitoring program and ensure the safety of bridge in construction process, to ensure the bridge into the linear meet the design requirements.
