Abstract The paper discussed the co nst ructio n technolog y of pre-tensioned prest ressed concrete hol low plate beam f rom the techno logic principle, characteri stic and const ruction technique. Wo rked out the w orking methods about technologic equipment s and technologic process. For cont rol the concrete quali ty to ensure tensio ned quality o f the beam , used the double cont ro l methods, that is: to co ntrol the check betw een the tensio ned st ress and ex tenison va lue.
