摘要
现浇箱梁有很多优点,但由于预应力现浇箱梁属于超静定结构,造成和简支梁不一样的受力特点,其施工工艺较复杂,技术要求比较高。本文重点对预应力现浇梁施工的工艺和在施工过程中质量控制做进一步的讨论。
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 .
