The application of aperture pipe shed support in under digging pedestrian underpass at shallow depth

Combined with pedestrian underpass project of Huanshan road,Yantai city,support scheme of the under digging pedestrian underpass at shallow depth was analyzed,and the structure and implementing mode of aperture pipe shed support was discussed.Mechanical analysis of the Finite Element Mode was done by the software of ANSYS.The result is combining with ductule the aperture pipe shed support can resolve the subsiding problem of road surface of the main artery in city effectually,and the result is in accord with the experimental result.
