SCHEMES AND IMPLEMENTATION OF MONITORING OF SUPER-LARGE DEEP FOUNDATION PIT DEFORMATION

The foundation pit of a research and development center covers a total area of more than 70 000 m2 and is 16 ～22 m deep.To guarantee side slope safety during excavation,horizontal displacement of side slope and ground settlement are monitored.The monitoring method can give adequate indication of side slope displacement and deformation of foundation pit,so as to timely detect displacement saltation and adopt treatment measures.
