Abstract
Cast-in-situ box girder has many advantages, but because of the prestressed cast-in-place box beam belongs to hyperstatic structure, caused different stress characteristics fro-m simply supported beam , its construction technology is com-plex, technical requirements are higher. This paper makes a fu-rther discussion focused on the construction process of cast-i-n-place prestressed beam and quality control in the constructi-on process .关键词
