摘要
介绍深盐二通道高架桥先简支后连续箱梁的施工方法和技术特点,提出了采用工程结构调整缩短施工周期方法,结合实际的高架桥箱梁施工技术,较好地完成了箱梁由简支向连续的体系转换。同时通过对现有临时支座的优化设计,从结构的可靠性、造价、施工等因素出发,选取较合理的临时支座。
The author introduced construction methods and technical characteristics of box-girder from simple frame to continuous frame, which were used in Shen-Yan No. 2 passage viaduct. Meanwhile the construction way that engineering structure should be adjusted to shorten the construction period was put forward. In this case, practical box-girder bridge construction technologies were adopted. Therefore the system of box-girder is transferred from simple frame to continuous frame. Moreover, present temporal support is improved while being designed, and appropriate temporal support is adopted, depending on the factors including the reliability of constructing, building cost and practical construction.
