| 鐵路鋼桁梁橋疲勞檢算三線系數(shù)(27 卷) |
| 英文標(biāo)題 |
| Trilinear Coefficient for Fatigue Computation of Railway Steel Truss Bridge |
| 摘要 |
| 我國鐵路正準(zhǔn)備修建三線橋甚至四線橋，現(xiàn)行規(guī)范及研究只涉及到兩線橋的疲勞檢算。將三線鐵路橋梁列車相遇的復(fù)雜隨機過程問題簡化為較簡單的概率問題，推導(dǎo)出鐵路三線鋼桁梁橋列車兩兩相遇概率及相遇次數(shù)、三線相遇概率及相遇次數(shù)，通過模型處理和簡化，推導(dǎo)出三線鋼桁梁橋疲 |
