| 摘 要： | 黄河某特大曲线桥架桥机采用牛腿支承,牛腿预埋在桥墩中,为了保证施工中的安全,对牛腿部分进行有限元模拟,分析牛腿及附近混凝土应力情况。应力计算采用ANSYS通用有限元程序,针对计算结果,提出牛腿改进方案。对改进后牛腿进行应力分析,根据前后方案对比,得出改进后方案满足施工要求。并为其他桥梁施工中,牛腿的设置提供参考依据。

| Abstract: | A Huanghe curved girder bridge fabrication machine is arranged on the cantilevers bracketed at the outer sides of the piers.To ensure the construction safety,stresses of the brackets and concrete nearby are calculated by the FEM program ANSYS.The calculating result shows that the brackets have not met the construction requirements.Some improvement measures should be taken for the brackets.Then the stresses are calculated on the improved brackets,comparison two schemes show that the unreasonable details in t... |
