Design and Engineering During the Construction of Los Leones Station (Line 6, Santiago Subway, Chile)

摘要

Los Leones Station, which belongs to the new Line 6 of Santiago Subway, is 19 m wide and is divided into two sections. The East Station Tunnel has 50 m of length and the overburden height is only 17 m while the West Station Tunnel has 55 m length and has been built 6 m below the Providencia parking lot. Like the rest of L6 Stations, the East Station Tunnel has been built with SSV method but the West Station Tunnel has been built with SFG method in order to decrease the induced subsidence on the Providencia parking lot; which shows no damages after the construction.
