摘要
介绍了无粘结后张预应力钢筋混凝土的施工工艺流程、后张无粘结预应力混凝土结构的施工工艺及需重点注意的问题,并分析了其目前存在的不足,同时论述了无粘结预应力钢筋混凝土结构能顺利张拉前的裂缝控制。
The construction technology and procedure of unbonded pos-tensioned prestressed RC is firstly introduced as well as construction technology of unbonded prestressed concrete structure and questions deserving attention in construction process. Based upon analysis of questions existed practical measures are proposed for cracks control before extension construction.
