Abstract:

Base on the shaft construction of a subway station in Changchun, make a detailed analysis of the site monitoring data of the retaining structure and the ground surface settlement against the excavation process of the inverted side wall shaft. By using the FLAC-3D software of finite difference, the numerical simulation are conducted, thus, make a comparison with the site monitoring data, and summarize the deformation characteristics of the retaining structure and the surface deformation of the inverted side wall shaft during the excavation. Results show that the support of the inverted side wall shaft which adopting alternation excavation and supporting while excavating has good stability, and the monitoring result is close to the numerical simulation’s, which provides the basis for the success of the engineering.The research results can be references for other similar designs and constructions.
