吹填区大跨度地铁深基坑施工技术

Construction Technology of Deep Foundation Pit for Long Span Metro in Land Reclamation Area

结合厦门市轨道交通3号/4号线工程,通过对沿线基坑地质条件和施工难点进行分析,提出相适应的基坑开挖方法以及施工难点的解决措施,并提出深基坑施工时应注意做好开挖与支护控制、施工监测等工作,最终本工程取得了良好的施工效果,保证了施工安全。可为相关工程提供参考。

Based on the Xiamen city rail transit line 3 and line 4 project,through the analysis of geological conditions and construction difficulties along the foundation pit,this paper puts forward appropriate excavation methods and solutions to construction difficulties,and presents that the control of excavation and support and construction monitoring should be paid attention to during the construction of deep foundation pit.Finally,the project has achieved a good construction effect,to ensure the safety of construction.It can provide reference to related engineering.
