摘要
随着装配式预制小箱梁广泛地应用到高速公路的建设中,对其下部结构的近似计算变得尤为重要。主要研究了不同单孔跨径和单联跨径数与墩顶水平力间的变化规律,近似地拟合了墩柱配筋率与跨径、墩柱高度间的公式。
With the prefabricated small box girder widely used in highway construction,the approximate calculation of its substructure is particularly important.The variation rules between the horizontal force on the top of pier and different spans or the span numbers of linked bridge were studied,and the formula between the reinforcement ratio of the pier and the span or the height of pier was fitted approximately.
