摘要: 基于梁格的基本理论,归纳了适用于梁式桥梁格模型的边界条件,提出了相对于常规的板壳、实体单元分析方 法的优势与不足,并从梁格网格划分和截面特性计算等方面阐述了梁格模型简化的要点,最后通过实桥算例分析与 荷载试验结果的对比,验证了梁格模型分析方法的有效性和适用性。

关键词: 梁式桥, 梁格模型, 荷载试验

Abstract: Based on the principles of grillage model,the boundary conditions and the advantages and weaknesses of grillage method compared with the shell or solid element analysis were summarized. The points to simplify grillage model were illustrated from grillage meshing and sectional characteristic,and the effectiveness and applicability were verified after comparing the analysis of a bridge example with the results of load test.

Key words: beam bridge, grillage model, load test
