Abstract

P.C box bridges is divided into internal prestressing and extermal prestressing based on arrangement of tendon. In this research the method of establishment of dviation block in advance and analysis of block and the control relationship of tension of external tendon and displacement should be examined by practical example of high speed rail way in aspects of maintenance and repairment.
