| 摘 要： | 针对施工索桥的修建对野三河大桥施工的影响,基于非线性有限元的理论对其进行了施工全过程计算分析,计算分析结果表明:施工索桥的修建对主墩变形和最大悬臂状态的T构受力的影响较大,对临时横撑与桥墩连接部位的局部混凝土的受力极为不利,施工索桥荷载作用下混凝土收缩徐变效应明显. |

| Abstract: | According to the influence of the construction of the construction cable bridge to the construction of Yesanhe Bridge,the paper carries out the calculation analysis of the whole construction process based on the nonlinearity finite element theory,the calculation analysis shows that the construction of the construction cable bridge has the great influence on the deformation of the main pier and the T-frame force of the maximum cantilever status,is unfavorable to the local concrete force in the connection of the temporary brace and the pier,the effect of the shrinkage and creep of the concrete is obvious under the loads of the construction cable bridge. |
