Shield First Stations To The Construction Of The Column Subway Station

Nowadays, one of the key problems beleaguering Beijing subway construction is the contradiction between station construction and space interval shield construction. The exploratory of possibility of shield-driven tunnel going forward, then, continuing station on that base is so necessary.Based on Sanyuanqiao station test section in one installment project (Olympic embranchment include) of Beijing subway line 10, mechanical analysis is done by FLAC^2D finite element software to the scheme of the construction of the subway station with shield method and Open Cut method. First of all, find out the key working procedure which affects the whole scheme by the contrast calculation with the two construction schemes, then, make a farther research disquisition on the chosen scheme considering with construction difficulty and risk, at last, calculate and analyze by finite element software with the hope of applying a reasonable and doable new scheme for the design and construction of subway station in our country.
