体外预应力加固大跨度连续刚构桥质量控制

摘要

以广州某特大桥加固工程为例，介绍了体外索加固连续刚构桥的施工监理控制要点和措施，包括原材料质量控制，转向块质量控制，体外索张拉质量控制等方面的内容，从而保证了桥梁结构的安全性。%Taking the reinforcement engineering of a bridge in Guangzhou for instance, introduces the construction quality control points and measures of external prestressed reinforce long-span continuous rigid frame bridge, including material quality control, steering block quality con- trol and external prestressed tension quality control, so as to ensure the safety of bridge structure.
