| 填芯法加固双曲拱桥的有限元分析及运用(50 卷) |
| 英文标题 |
| Finite element analysis and use of reinforcing two-way curved arch bridge by cancelling transverse curve (filling method) |
| 摘要 |
| 对于我国上世纪60、70年代曾广泛建造的双曲拱桥的加固方法进行了分析研究，重点讨论近几年在实际加固工程中运用较多的填芯加固法，并以一座用填芯法加固的桥梁为例，用有限元程序建立桥梁模型，计算并对比加固前后控制截面的承载能力水平，分析填芯法加固双曲拱桥的合理性与 |
