摘要
某桥梁工程的结构形式为31.5m+35.5m+50.5m+35.0m+31.5m预应力混凝土连续箱梁,通过结构分析程序对连续箱梁体外束加固前后总体和局部受力进行验算分析,验证该桥加固前后结构受力的安全性和保证桥梁营运阶段结构性能的适用性和耐久性。
As for the prestressed continuous box girder with such spans as 31.5 ＋35.5 ＋50.5 ＋35.0 ＋31.5m, Checking analysis on the overall and local stress of the external strand of the continuous box girder before and after strengthening has been conducted with structural analysis programs, to verify the safety and ensure the serviceability and durability of the bridge in operation.
