Study on Deformation Monitoring of Subway Station Deep Foundation Construction

Abstract:

This paper deals with the construction of the foundation pit of the East Station of Meixi Lake, belonging to Reme Area underground supporting transport system of Changsha, China. A description is given of the deformation monitoring of the open excavation. During site operations, the construction process monitoring data are continuously analyzed. It has been found that the deformations induced by the excavation of the foundation pit have some influence on the surrounding buildings. Monitoring of both horizontal pile-top displacement and ground surface settlements are extremely important to ensure safety of the neighboring constructions. Based on the monitoring information gathered during construction, engineers should adjust construction parameters to optimize the design at any moment, and adopt effective treatment measures to ensure the follow-up constructions can safely and successfully complete.
