摘　　要：福州地铁船政文化城站基坑周边环境较为复杂,车站基坑属于超大圆形深基坑,对于基坑的支护结构要求高,因此基坑施工风险等级较高,且施工技术难度大。在设计基坑支护结构时,需要充分考虑使得结构有利于减少基坑变形、降低支护结构内力以方便后期施工。采用数值计算,分析单个因素对结构内力的影响,为工程支撑设计提供参考,并为今后类似工程的修建提供借鉴。The surrounding environment of the foundation pit of the Fuzhou metro shipbuilding culture city station is relatively complex,and the station pit is a large circular deep foundation pit,which requires high requirements for the support structure of the foundation pit,so the construction risk level of the foundation pit is extremely high and the construction technology is difficult.Numerical calculations are used to analyze the influence of individual factors on the internal forces of the structure,to provide a reference for the design of the engineering support and to provide a reference for the construction of similar projects in the future.
