Abstract

Abstract:

The traditional mining method can not meet the requirements of tunnel construction in complex geology and area with multiple risk sources. As a result, the steel tube slab (STS) pipe curtain method, a new construction method for ultrashallow buried metro stations is proposed. The drag reduction by grouting, soil cleaning between steel tubes, bolt connection, concrete pouring and ground surface settlement during pipe jacking of a metro station in Shenyang constructed by STS pipe curtain method are studied by field test and monitoring. And then a series of problems have been solved; a series of technologies have been developed; therefore the successful construction of mined metro station by STS pipe curtain method has been guaranteed.

Key words: steel tube slab (STS) pipe curtain method, ultrashallow buried mined metro station, steel pipe jacking, drag reduction by grouting, concrete pouring, ground surface settlement
