摘要
某预应力混凝土连续箱梁桥施工中出现裂缝,从设计与施工两方面分析原因,并提出裂缝加固设计的具体意见。实践证明,适当的设计改进和严格的施工质量控制是成功的。
The problem of cracking in a continuous prestressed concrete box girder bridge occurred during the construction.The causes leading to the cracking are analyzed from both aspects of design and construction,and specific proposals to improve the design and to handle the cracking are made.It has been proved that properdesign improvement and strict quality control in the construction are successful.
