Abstract：
The bending and anchorage areas of broken-line pretension prestressed concrete box beam have complex stressing conditions and concrete cracking often happens. This paper introduced the construction process of pretension prestressed concrete box beam, analyzed the complex stressing conditions at bending area and described the key points in construction. Theoretical references were provided for practical construction.
