This design is mainly for a deep foundation pit during the construction of
foundation pit deformation and cause the deformation of the surrounding environment
monitoring methods and data processing program design and analysis.The main
monitoring content of the foundation pit wall for monitoring horizontal displacement
and settlement monitoring;In support of lattice column for subsidence monitoring; near
an excavation foundation pit surrounding by effect of buildings for subsidence
monitoring;The surrounding building settlement of super early warning value
requirements of the tilt observation.The monitoring method for precision two level, the
polar coordinate method, points method,And its feasibility was made precision analysis.
