以两跨单箱四室钢筋混凝土连续箱梁桥为研究对象,建立平面杆系、空间梁格以及三维实体模型,通过各模型计算结果比较,指出宽跨比相对较大的连续箱梁桥各计算模型的差异;探讨了梁格法纵、横梁的具体模拟方法;另外,对宽跨比相对较大的连续箱梁桥计算方法提出建议,其分析结论对同类桥梁的设计计算具有一定的参考价值。
Taking the two-span single box four-story reinforced concrete continuous box girder bridge as the research object, the plane bar system, the space bar system and the three-dimensional solid model are established. Comparing the calculation results of each model, it is pointed out that the continuous box- The difference between the model and the model was discussed. The concrete method of longitudinal and crossbeams was discussed. In addition, the calculation method of the continuous box girder bridge with relatively wide span ratio was put forward. The conclusion of the analysis is of certain reference value to the design and calculation of similar bridges.
