在对曲线段上预应力混凝土T梁桥设计方法进行介绍的基础上,建立了梁格模型,在对称和偏心车道及车辆荷载作用下对中横隔梁设置方式差异造成的影响进行计算比较分析,结果表明中横隔梁设置方式差异对桥梁结构受力状态影响很小,可忽略不计。另外,随着新规范的运用,采用车道荷载及车辆荷载加载对横隔梁进行受力分析,结果表明车道荷载加载结果与偏心压力法计算的横隔梁竖向弯矩结果相近,远大于车辆荷载加载所产生的竖向弯矩结果,对以后设计有一定的借鉴作用。
Based on the introduction of the design method of prestressed concrete T-beam bridge on curved section, the beam lattice model is established to calculate and analyze the influence caused by the difference of the setting modes of the middle-side beam under the symmetric and eccentric lane and vehicle load The results show that the difference of the setting modes of the middle diaphragm beams has little effect on the stress state of the bridge structure and can be neglected. In addition, with the application of the new code, the load analysis of the beam with lane load and vehicle load is carried out. The results show that the result of loading of the lane load is similar to the vertical bending moment of the diaphragm beam calculated by eccentric pressure method, The result of vertical bending moment generated by load loading has some reference for future design.
