摘要
本文指出了当前无粘结预应力混凝土结构设计与施工中存在的若干问题，并对预应力筋锚具组装件的选择、锚固区在结构物中的设置、对组装件的密封要求、停止使用三种不良锚具以及设计中应明确给出张拉力等问题提出了建议。
Some common problems existing in design and construction of unbonded prestressed concrete structures are pointed out in the paper Meanwhile,the proposals for the selection of prestressing tendon anchorage assemblys,the set up of anchorage zones in structures,the sealing requirements for tendon anchorage assemblys,as well as suspension of using three types of unqualified anchorages and the prestressing force which should be given clearly in design,etc have been presented
