摘　　要：介绍了缓粘结预应力技术在力鸿生态家园公寓高层结构大跨度板中的应用,给出了缓粘结预应力混凝土板的设计和施工方法,指出了缓粘结预应力技术施工中应该注意的事项,通过工程实践总结出了缓凝胶粘剂固化时间的控制和张拉时间的控制是缓粘结预应力施工过程中最关键的问题,为缓粘结预应力工程施工提供了参考。It is introduced the application of retard-bonded prestressed technique to high-level structure of large-span slabs of Lihong Ecology Homeland project, put forward the design method and construction craft of retard-bonded prestressed concrete plate, and pointed out that the matters needing attention in construction of retard-bonded prestressed concrete technique. According to the practice, it is concluded that the control over the curing time and pull-time of relief binder is the most critical issue in retard-bonded prestressed concrete construction process. Which can give a reference for retardbonded prestressed concrete construction.
