According to the characteristics of railway station reconstruction project near the existing lines in con-struction,the unilateral grading jump construction schedule was put forward with canopy beam string structures. Through the finite element software midas/civil to establish the simulation model and field monitoring of high pre-cision of total station with reflecting film,the difference of control nodes form between the theoretical results and measurement of unilateral tension of steel beam string structure was analyzed in the construction process.Mean-while,the construction scheme of beam string structures should be adjusted and optimized in time so as to ensure the geometry form of beam string structure and construction quality at each node.In this way,good technical benefits can be achieved,thus it has reference significance to similar beam string structure construction.
