Abstract:

Opencut slopes of 1:0.3 gradient reinforced by soil nails and prestressed anchoring cables are adopted for the foundation pit of Shaoniangong station of phase 1 of Shenzhen Metro. On basis of the requirements of the design and construction of the station, ground surface settlement, horizontal displacement of ground, stress of soil nails and anchoring cables, water table and rebound of foundation floor are monitored. By means of analysis on and prediction and feedback of the monitoring results, reliable reference can be provided for the informationaided design and construction of Metro stations.
