ECONOMIC COMPARISON AND SELECTION OF SHIELD METHOD AND MINING METHOD IN SHIJIAZHUANG METRO TUNNEL
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.
