简支转连续小箱梁的支承形式包括单排支承和双排支承,本文主要分析了双排支承结构形式小箱梁在支座刚度、支座间距不同的情况下其内力及反力的变化规律,为双排支承结构的研究、设计以及施工提供了一定的参考作用。
The support form of simply supported continuous small box girder includes single-row support and double-row support. In this paper, the change of internal force and reaction force of double-row support structure small box girder with different support stiffness and bearing spacing are analyzed The law provides a reference for the research, design and construction of double-row support structure.
