摘要
当矮塔斜拉桥主梁采用悬臂法施工时,为保证桥梁的稳定性和安全性,需对主梁进行临时固结.建立4种Midas civil模型模拟某矮塔斜拉桥的临时固结体系,对不同模型的计算结果进行对比分析,从而得出与实际情况最为符合的模拟方案,为以后的临时固结体系模拟提供参考,更好地对施工过程进行指导与控制.
To guarantee the stability and safety of a bridge, a temporary consolidation is of great importance to main when cantilever construction method is used in constructing an extradosed cable-stayed bridge. Four kinds of Midas models are firstly built to simulate the temporary consolidation system of a short tower cable-stayed bridge. The results ofdifferent models are, then, compared and analyzed to get a simulation scheme which is the most consistent with actualsituations. This can shed light on future simulations of temporary consolidation systems, process and controls.
