摘要： PC工法桩作为一种新型绿色的支护体系已在建筑施工中较多应用，然而在地铁车站中的应用与研究仍然有限。以福州地铁车站附属结构工程为依托，通过理论研究、现场应用并结合监控量测，分析了软土地层地铁车站附属结构中PC工法桩施工的重难点，研究了PC工法桩施工关键技术。实践证明，①钢管桩与车站主体结构接驳处极易形成渗漏水通道，需要加强接缝处止水帷幕施工质量控制。②施工需做好回填土选择及压实度控制。③PC工法桩具有施工速度快、止水效果快、主材可回收利用、经济环保等优点，综合效益提高了近20%。④PC工法桩在本工程中得以成功应用，可为类似地层地铁车站附属结构施工中的推广和应用提供参考。

Abstract: As a new green excavation supporting system, the PC (Pipe-Combination) pile method is widely used in construction in Shanghai and Zhejiang, but its application and research results in subway station construction are still rarely reported. Based on the design and construction characteristics of an auxiliary structure of Fuzhou Metro station and the construction principle of the PC pile method, this study analyzes the key and difficult aspects of the construction of PC pile method in the auxiliary structure of metro station in soft soils by means of theoretical research, field application, monitoring and measurement. The key aspects of the PC pile methods are also introduced. Practice has proved that, compared with the traditional subway supporting structure, the PC pile method improves the comprehensive benefits of the construction progress, quality, environmental protection and cost by nearly 20%. This method positively responds to the national “double carbon” strategic goal and has a wide range of application value in other excavation supporting projects.
