深度流塑层大型预制T梁过桥及架设数值模拟应用研究

Applied Research on Numerical Simulation of Large Precast T-beam Bridge Crossing and Erection in Deep Flow Plastic Layer

为了保证大型预制T梁运输过桥及架设的施工安全性,需要对T梁运输过桥及架设过程进行整体的数值模拟分析。结合温岭泽国—玉环大麦屿疏港公路工程,采用有限元软件Midas Civil建立梁桥空间梁单元检算模型进行相关分析,表明利用数值模拟分析预制T梁过桥及架设具有可参考性。

In order to ensure the construction safety of large precast T-beam transportation bridge crossing and erection,it is necessary to carry out the overall numerical simulation analysis of T-beam transportation bridge crossing and erection process.Combined with Wenling Zeguo-Yuhuan Damaiyu highway project,the spatial beam element validation model of beam bridge is established by using the finite element software Midas Civil for correlation analysis,which shows that the numerical simulation analysis of precast T-beam bridge crossing and erection can be used as a reference.
