摘要
盾构法与矿山法是地铁区间主要的施工方法,施工方法是影响地铁造价的主要因素之一。以石家庄地铁4号线为例,建立了石家庄地铁区间盾构法与矿山法的造价公式。通过比选石家庄地铁盾构法与矿山法的经济性,得到了盾构法与矿山法的经济性指标均为线性的结论,同时区间短于562 m时采用矿山法的经济性优于盾构法。该研究方法可为其他城市地铁区间施工方法的选择提供参考。
Shield method and mining method are the main construction methods in metro tunnel sections,and construction method is one of the main factors affecting the cost of subway construction.The Shijiazhuang Metro Line 4 was taken as an example to establish the cost formulas for the shield method and mining method in the Shijiazhuang Metro section.By comparing the economic performance of the shield method and the mining method in Shijiazhuang metro,it was concluded that the economic performance indicators of the shield method and the mining method are both linear.At the same time,the economic performance of using the mining method is better than that of using the shield method when the interval is shorter than 562 meters.This research method can provide reference for the selection of construction methods for metro tunnel sections in other cities.
