摘要
为研究节段预制胶结拼装结构在正常使用阶段和施工状态下的结构行为,结合架梁工况,以模型试验梁模拟其正常使用的荷载工况,测试试验梁的主要静力反应和应力状况,从而验证铁路胶接缝节段拼装结构的结构形式、构造的受力可靠性、安全储备、与相关规范的符合程度。此研究具有一定的理论意义和工程实践应用价值,对同类工程具有一定的借鉴意义。
To study the structural behavior of the section-assembled glue-jointed structures both at the normally-used stage and in the state of construction,the true loading condition of it in normal use is simulated,upon the basis of considering the erection construction conditions,with the help of a test model girder,with the main static response and stress condition of the test model girder tested to testify the structural forms of the section-assembled railway glue-jointed structure,the mechanical reliability and the safe reserve of the structure,and the degree of its conformity to the relevant specifications.The research of ours is of certain theoretical and practical engineering importance and may serve as a useful reference for other similar projects.
