摘　　要：以国内率先采用的盾构法扩挖地铁车站工程为研究对象,从技术可行性和经济性的角度,对比分析了矿山法与盾构法2种施工方法。通过分析2种施工方法的费用组成,对比研究了二者的工程数量、工程费用和综合造价指标。研究结果表明,以实际工期反推掘进机械台班计算得出的盾构法综合造价指标比矿山法减少了4.84万元/m,降幅达16.60%。该结论可为类似特殊地铁车站建设工程的技术比选和工程造价研究提供参考和借鉴。Taking the shield tunneling subway station project as the research objectin China, the two excavation methods of mining method and shield method are compared and analyzed fromtechnical feasibility and economy aspects. By analyzing the cost composition of the two methods, the engineering quantity, engineering cost and comprehensive cost indexesare compared. The results show that the comprehensive cost index of the shield method obtained by the calculation of the machine shift and based on the actual construction period is 48 400 yuan/meter less than that by the mine method, with a decrease of 15.36%. It can provide reference for the technology selection and project cost research of similar special subway station projects.
