Effect review of the Strengthening Technique by Use of the External Prestressing

摘要：

　　The grand bridge of Fu Feng is prestressed concrete cross-section continuous girder,which is reinforced with extemal prestressing.Construction monitoring is based on the measured data,and using the finite element method to calculate,it need to analyze the control of the stress and deflection in the construction to ensure to make the construction could be completed on schedule and to reach an ideal type.The field monitoring result indicates that the type of bridge did improve and reach the requirement of design after reinforcement.
