| 英文標(biāo)題 |
| Finite element analysis and use of reinforcing two-way curved arch bridge by cancelling transverse curve (filling method) |
| 摘要 |
| 對(duì)于我國(guó)上世紀(jì)60、70年代曾廣泛建造的雙曲拱橋的加固方法進(jìn)行了分析研究，重點(diǎn)討論近幾年在實(shí)際加固工程中運(yùn)用較多的填芯加固法，并以一座用填芯法加固的橋梁為例，用有限元程序建立橋梁模型，計(jì)算并對(duì)比加固前后控制截面的承載能力水平，分析填芯法加固雙曲拱橋的合理性與 |
