摘　　要：以湖北省地调科研大楼采用后张有粘结预应力混凝土梁为例,将屋面板的两榀主梁作为测试对象,对预应力摩擦损失、理论伸长值和实测伸长值的偏差、锚具变形量、跨中反拱值进行测试,结果表明,该后张有粘结预应力混凝土梁的设计和施工是安全可靠的。The post-tensioned cohesive prestressed concrete beams of Geological Survey R ＆ D Building of Hubei Province are studied. Two beams of the roof plate are taken as the test object and prestressed friction loss, deviation between theoretical extension value and actual extension value, anchor deformation and midspan anti-arch value are tested. Test results show that design and construction of the post-tensioned cohesive prestressed concrete beams are safe and reliable.
