By emptying the above mentioned theoris and conclusions, this paper introduces detailedly the whole process of the compare and selection of cangzhou city gongrong road canal bridge ' s plan, design calculation and check of structure. the internal force calculation of the bridge adopts the program of plane member system ( bricas ), and it was checked by the program of brcad
本文最後應用上述理論和結論,以大量篇幅詳細介紹了滄州市光榮路運河橋(下承式鋼管混凝土
系桿拱橋)從方案比選到結構設計和計算、驗算的全部過程,以及施工中的要點,本橋內力計算採用平面
桿系有限元計算程序, (交通部公規院的《橋梁設計綜合計算程序》 ( bricas4 . 0 ) ) ,並採用空間有限元程序( brcad2 . 0 )進行驗算。
Only 1, 000, 000 vehicle crossings produced significant cracking in the floor beams of the tied arch span and in the plate girders of the approach spans.
僅通過1,000,000輛車就在
系桿拱的橫梁中以及引橋的板梁中造成明顯的開裂。
