以某钢砼组合箱梁桥为工程实例,分析其临时墩失稳产生的原因,采用有限元程序全面模拟计算桥在各个状态下的受力情况并与实际状况相互比较验证,最终评估其对整桥结构的影响。
Taking a concrete-filled steel-concrete composite girder bridge as an example, the reasons for the instability of temporary pier are analyzed. The finite element program is used to simulate the bridge’s force under all conditions and verify with the actual conditions. Finally, The impact of the entire bridge structure.
