通过对某座预应力混凝土现浇连续箱梁的支座反力计算,总结出用“鱼骨”的力学模型来计算分析箱梁的支座反力,该方法建模简单,计算结果准确,对直线及曲线桥梁的支座反力计算均可使用。
By calculating the reaction force of a prestressed concrete box-cast continuous box girder, it is concluded that the reaction force of box girder is calculated by using the mechanical model of “fishbone”. The method is simple in modeling and the calculation result Accurate, the linear and curved bridge bearing reaction can be used.
