摘要
对独柱墩桥梁上部结构横向倾覆进行了验算,然后采用静力非线性方法对桥梁的实际倾覆过程进行仿真分析,并对二者的验算结果进行深入探讨,提出了几点建议。
The Stability against overturning problem of concrete continuous box girders with single- column pier is checked. And a static nonlinear method is adopted to simulate the actual overturning process,which provides a comparison to the result of checking calculation method.And then some suggestions are given for the further study and design.
