Abstract This paper mainly introduced the cause and characteristics of deformation observation and the content, purpose and meaning of high-rise building deformation observation and the role of the high-rise building settlement observation.This paper designed elevation control network layout scheme on the settlement observation with the selection and layout of the selection and layout. This paper also elaborated the frequency and accuracy analysis of settlement observation .It put forward several kinds of methods of deformation observation.Selecting a few problems of observational methods that needs attention and consideration .This paper proposed the theory and method of high-rise building settlement observation data analysis,as well as the bench mark stability analysis.

Combined with the actual engineering -- Shenyang aviation equipment training base officer dormitory 3# floor of engineering examples, the high-rise building and settlement observation of observed data of adjustment calculation;Introducing the engineering geological structure and foundation;The stability of standard basis points inspection and analysis; In each of the sedimentation value calculation is get subsidence and the basis of accumulative value and rendering (p-t-s load, time, settlement) diagrams, settlement isoline accumulated over time, each observation the subsiding speed curve. Through analysis of subsidence observation data with time, draw some useful and practical conclusion.

Key words: High-rise buildings; Settlement observation; Data analysis
