| 以鋼橫梁受力為主的拱橋橋面系病害分析與加固方案探討(50 卷) |
| 英文標題 |
| Defect analysis of arch bridge deck system with major force beared by steel cross beam and discussion on strengthening scheme |
| 摘要 |
| 介紹了以鋼橫梁受力為主的鋼管混凝土拱橋橋面系出現(xiàn)病害的情況，分析病害產(chǎn)生的原因為超載車輛作用，以及鋼縱梁參與了結(jié)構(gòu)整體受力，導致了縱橫梁連接部位焊縫處存在較高的應力幅，出現(xiàn)了材料的疲勞破壞，進而對采用大縱梁體系的加固方案進行了深入的探討。 |
