Reliability Study of Excavation Safety in Underground Space of Chen Clan Academy Square
Chen Clan academy square reconstruction project is one of the Asian Game projects.The depth of the foundation pit of the green square is about 12.l m.The difficulties of the excavation are the protection of the ancient buildings of Chen Clan academy and the surrounding buildings and the relatively short construction period.Thus, a top-down construction method was selected as the final method.For security, reliability analyses based on Taylor series technique have been performed to the factor of safety of whole stability, stability against overturning, stability against basal heave and stability against seepage.The results show that the design of the supporting structure is generally reliable, but there are also some potential safety hazards which should be noticed.The application of Taylor series technique also shows the simplification and practicality of this method.
