Abstract：A general summary is given to the state of the art and the essential features of the modern PC beam bridges in China, including the current application of the prestressing systems and techniques. Some problems that need to be solved in the engineering practice are discussed and investigated. In the end, suggestions and comments for improving our technology on PC beam bridges as a whole and the trends for future dsvelopment are pointed out.
