对于大跨连续刚构桥的高墩,其稳定计算十分必要。本文以大溪丰大桥为例,对施工阶段不同荷载作用下高墩稳定性进行分析,得出该种结构在不同施工阶段稳定性能的特点,供该桥梁施工参考。
For tall piers of long span continuous rigid frame bridge, its stability calculation is very necessary. Taking Daxifeng Bridge as an example, the stability of high pier under different loads in construction stage is analyzed. The stability characteristics of this kind of structure at different construction stages are obtained for the construction reference of the bridge.
