Then, based on the theory of creep and shrinkage, the simplified calculation of the time-dependent deformation is brought forward. Through the comparison and analysis, Both the effects of creep and shrinkage should been taken into account in the field measurement and the calculation results are in good accordance with the field measurement results.Keywords:high building; SRC transfer beams; field measurement; time-dependence deformation*安徽省教育廳青年基金資助(基金號：2006jq1066)。
