摘要
独柱墩弯箱梁桥在重车偏载作用下存在倾覆失稳的可能性。文章针对广州某立交F匝道桥,利用Midas/Civil对其抗倾覆稳定性进行分析,并给出针对性的加固改造措施,其荷载选取、验算准则和加固方案可供类似桥梁工程加固参考。
Curved box girder bridges with single-column pier may suffer overturning under eccentric load caused by heavy-duty trucks. Taking a interchange ramp bridge F in Guangzhou as an example, the anti-overturning stability of acurved box girder bridge with single-column pier is analyzed using Midas/Civil. The corresponding strengthening methods are proposed, the loading selection, checking criterion and strengthening methods could be taken as reference for the similar bridge strengthening.
