| Abstract: | By combining with factual projects,the paper introduces the construction technique of back-tension adhesion-free prestress frame beam,illustrates the quality measures,explores common treatment for accidents,and points out the construction technique of back-tension adhesion-free prestress frame beam can transmit the presstress by the anchorage of the both ends,so it can be applied in the tension of the back-tension curve of the cast-in-place frame beam. |
