| Nanjing subway south-north line TA 12 section interved tunned between drumbuilding and Xuan Wu door,formed from Guround two tunnels.This interval tunnelsection is complex and changeful , forms to exceed little span tunnel , also has spantunnel , this interval tunnel pass through under the building cround new two sides onthe road mainly , line passes through major is â… or â…¡ kind surround rock.According to the technical baffling problem that met in construction, study mainlyfrom two aspects:Major construction technical measure , soft flow to mould layershallow bury dark dig tunnel construction technical measure . This paper elaboratesSoft flow to mould the note technology of thick liquid in layer tunnel,Anchor rodpresses stake and the interval tunnel digging technology. Through the research forsome of technologies,get city subway under complex address conditions, intervalconstruction technology;city subway and city underground project, soft flow to mouldlayer dark dig the note technology construction parameter of thick liquid in tunnelhole science and technology and so on. Solve land table efficiently to subside,Subway interval tunnel construction and tunnel construction are for the bafflingproblem such as the influence of city building. Through actual application and theresearch of some of technologies. It accumulates rich construction experience for us incity subway and city underground construction field. and at the same time also thatthis enterprise creates better economic benefits and social benefits.
