文章采用空间梁格单元进行曲线折梁和直线梁上下部整体建模对比计算。结果表明,多孔曲线折梁桥各墩台顶水平力分配计算按展示直线桥和曲线桥计算时有差异。差异的大小主要与曲线半径、跨径、孔跨数、墩高差等有关。对斜桥、曲线或曲线折梁桥,尤其是墩高差异大的桥梁应按空间有限元建模进行计算,以确定各墩顶纵横桥向水平力的大小。
In this paper, the spatial beam unit is used to calculate the bending of the curve and the overall modeling of the upper and lower parts of the linear beam. The results show that the calculation of the horizontal force distribution at the pier tops of the multi-folded curved bridges shows differences when calculating the straight-line bridge and the curved bridge. The main difference with the size of the curve radius, span, hole span number, pier height difference and so on. For inclined bridges, curved or curved bridges, especially those with large differences in pier height, the finite element modeling should be used to determine the horizontal force of vertical and horizontal bridges at each pier top.
