摘要
对于高墩大跨连续刚构桥,确保桥梁的稳定性是十分关键的问题。以某高墩特大桥为例,建立Midas空间计算模型,基于稳定性理论,得到该桥成桥阶段和施工最大悬臂阶段的稳定计算结果,并通过计算,探讨了影响高墩稳定性的主要因素,得到一些有益的结论。
It is a critical issue to ensure the stability of bridge for high- pier long- span continuous rigid frame bridge Taking a high- pier bridge as an example,the MIDAS space calculation model is established.Based on the stability theory,the stability calculation result is achieved in the completion stage of this bridge and the largest cantilever construction stage,And the main factors influencing the stability of high pier are discussed according to the calculation.Some beneficial conclusions are achieved.
