| 中文摘要: |
| 利用ANSYS软件，建立平面杆系模型进行双曲拱桥内力计算，并采用考虑混凝土非线性的三维实体单元进行主拱圈模拟，对加固前后的内力、应力和变形等进行了计算分析,得出采用锚喷混凝土把“拱型”结构变成“箱型”结构加固双曲拱桥，可以达到改善旧桥使用性能和提高荷载等级的目标。 |
| 英文摘要: |
| By using ANSYS software, the internal force of a double arched bridge is calculated according to the model of plane beam model, and the main arch is analyzed according to the model of the three dimensional solid element in order to acquire the internal force, stress and deformation of the double arched bridge. The conclusion from the calculations in this paper shows that by anchoring and shotcreting concrete the arch structure is turned into a box structure, achieving the objec tive of improving serviceability and increasing the load bearing capacity of double arched bridges . |
