| 某新建鐵路橋墩裂縫成因分析及承載力評定(51卷) |
| 英文標題 |
| Analysis of causes of cracking in pier for certain new-built railway bridge and assessment of its bearing capacity |
| 摘要 |
| 通過對某地方鐵路特大橋6個橋墩的外觀檢查和裂縫寬度、深度的測定，以及縱橫向頻率的檢測結(jié)果分析可知，所有裂縫均屬于溫度裂縫，對橋墩的縱橫向剛度未產(chǎn)生較大的影響；從靜力檢算的結(jié)果可以看出，在橋墩現(xiàn)有裂縫的情況下，橋墩的受力滿足中—活載的要求。 |
