| 摘 要： | 对一座主跨100m下承式拱梁组合桥进行拱脚结点空间有限元分析和光弹试验.结果表明,结点内部应力不大,设计时配筋不必太复杂,以节约材料、方便施工;而在刚度突变处、预应力锚点和支座处应力值较大,设计时要注意加强这些部位的构造措施与配筋.

| Abstract: | The space finite element analysis and the three dimensions photo-elastic experiment of springing joint of such bridge with a span of 100m are studied in this paper. The results show that the stresses inside the joint are small, so the reinforced bars inside the joint should not be too complex in order to save material and make convenient for construction. However, the stresses are large in the places where the rigidity changes abruptly, the anchorage devices or supports are acted. Therefore, the structure measurement and reinforcing should be strengthened in the design. |
