| 中文摘要 | 根据桥梁检测结果,准确、快速地预测桥梁承载力,对桥梁运营和维修具有重要意义.对基于非线性有限元软件的桥梁承载力预测技术进行了研究.首先介绍了精细建模技术,并通过大比例模型桥试验,证明了非线性有限元模型的准确性.为解决精细建模过于繁琐的问题,又开发了快速建模程序,以提高建模的方便性.最后,介绍了上述桥梁承载力预测技术的工程应用实例.; Fast and accurate prediction for the bearing capacity of bridges after inspection is important to the management and retrofitting of bridges.The prediction technology of the bearing capacity of bridges is studied based nonlinear finite element analysis.The accuracy of the proposed high-precision nonlinear finite element model is verified via a large scale bridge model experiment.And a fast modeling technology is developed to reduce the workload of high-precision modeling.Finally the application of the proposed technology is demonstrated with real projects.; 国家自然科学基金(50808106) |
