整体预制叠合梁设计及关键技术研究

Design of Integral Precast Composite Beam and Study of Key Technology

杭州市莫干山路高架桥采用全预制拼装工艺设计及施工,其上部结构主要采用多跨连续整体预制叠合梁。以该项目为研究对象,对莫干山路高架桥整体预制叠合梁工艺进行介绍,探讨其具体的设计内容。并针对该项目特殊性,对整体预制叠合梁负弯矩区处理方案进行比选,以期为类似情况项目的设计及施工提供一定参考。

The viaduct in Moganshan Road of Hangzhou is designed and constructed by the full prefabrication and assembly technology. Its superstructure is mainly the multi-span continuous integral precast composite beam. Taking this project as the research object, the technology of integral precast composite beam for the viaduct in Moganshan Road is introduced, and its detailed design contents are discussed.According to the particularity of the project, the treatment schemes of the negative moment area of the integral precast composite beam are compared and selected in order to provide some reference for the design and construction of the similar projects.
