摘要
三门口跨海大桥北门大桥为主跨270 m的钢管混凝土中承式拱桥,对该桥静力系数进行试验和数值分析,并对拱肋三分力系数进行雷诺数修正。验算大桥静风稳定性,结果表明,无论在施工阶段,还是在成桥状态,抗风稳定性均满足要求。
The Beimen Bridge of Sanmenkou Sea-Crossing Bridge is a half-through concretefilled steel tube arch bridge with a main span 270 m. The static force coefficients of the Bridge were tested and numerically analyzed, the three-component coefficients of its arch ribs were modified by Reynolds numbers and its static wind stability was checked by calculstion. The results indicate that the wind-resistant stability of the Bridge can meet the requirements both at the construction and completion stages.
