[提要]  有粘结预应力混凝土楼板的强度、抗裂度、抵抗灾害能力以及经济指标优于无粘结预应力混凝土楼板，但在设计上尚有待规范。结合国外规范及工程实践，作者认为我国规范对预应力筋的设计强度规定偏于保守需要予以修订，同时提出了有粘结预应力混凝土楼板拉应力控制、普通钢筋设置和间距的设计建议，以期在我国进一步推广该项技术。

This paper describes the advantages of bonded post-tension concrete slab over unbonded in many aspects, such as strength, disaster resistance and economical index. But its design method should be standardized. Author considers that the stipulation of tendon design strength in Chinese code(GBJl0 - 89)is conservative and should be revised. In order to spread the application of bonded post-tension concrete slab in China widely, author also gives some suggestions for bonded post-tension concrete slab, such as control of tensilestress, content and spacing of reinforcement.
