摘要
近年来,城市轨道交通工程邻接既有地下结构物进行邻接施工的工程大量涌现。在这种情况下,施工中对既有结构物的影响以及自身近距离施工时相互影响的安全评估已成为城市轨道交通工程施工中需要解决的关键问题。以合肥轨道交通3号线工程为例,针对城市轨道交通盾构隧道近距离下穿危大拱桥存在的主要风险及影响因素进行分析研究,提出相应的应对措施。
In recent years,urban rail transit projects concerning abutment constructions that abuts existing underground structures have been springing out enormously.Under this circumstance,the safety assessment of both the impact on existing structures and the interactive influence between each other from construction within close range have become the key problem to be solved.Hefei rail transit line 3 was adopted as an example,where the main risks and influencing factors of building shield tunnel passing through the dangerous large arch bridge were analyzed and studied,and the corresponding countermeasures were put forward.
