| 摘 要： | 在后张有粘结预立力的混凝土结构中，预应力筋的防瘩蚀问题及其与结构混凝土的共同工作问题是通过将水泥浆充满预留孔道和预应力筋之间的空隙予以解决的，因此，孔道压浆质量的优劣直接影响到预应力混凝土结构的耐久性和安全性：采用真空压浆技求是解决压浆不饱满问题的有效途径

| Abstract: | In the post-tensioned prestressed concrete structure, we usually fill the slurry up gap between reserved channels and prestressed tendons to solve the problems of anti-corrosion of prestressed reinforcement and work together between prestressed reinforcement and structural concrete, so duct grouting quality will affect the durability and safety of prestressed concrete structures. Vacuum grouting technique is an effective way to solve the problem of incomplete grouting. |
