摘要：

We found through the statistics of disease that the void is one of the major problems of the CFST in recent decades. In fact, the void is inevitable with the current state of materials and construction method. This paper describes detailedly many methods of repairing void from the two aspects of the existing bridge and the under-construction bridge, including secondary grouting method, longitudinal stiffening rib, inner flange, bell-shaped anchoring box, etc.
