本文以薄板有限元法为基础,对不同交角的平板和三孔连续大型箱形涵桥作静力分析。通过大量的数据及图表,清晰地揭示了斜交角度的变化对斜板和斜交箱形涵桥内力的影晌及其变化规律。本文还阐迎了斜板、斜桥不能按正板、正桥设计以及箱形涵桥必须按空间计算的道理。
Based on the thin-plate finite element method, the static analysis of the slab and three-hole continuous box-shaped culvert bridges with different angles is done in this paper. Through a large amount of data and charts, it clearly reveals the influence of the change of skew angle on the internal forces of the inclined plate and the skew box-culvert bridge and the variation rules. This article also expounds the reason that the inclined plate and the inclined bridge can not press the positive plate, the design of the main bridge and the box-shaped culvert bridge must be calculated according to the space.
