云南省某高速公路大跨度钢箱梁顶推滑移施工模拟分析研究

Simulation and Analysis of Pushing and Sliding Construction of Long Span Steel Box Girder of a Highway in Yunnan

随着云南省基础设施建设的开展,为响应国家绿色公路建设,减少工程建设对环境的破坏,降低高空作业的危险度,钢箱梁液压顶推滑移施工逐渐增多。工程根据实际情况进行了云南省某高速公路跨河钢箱梁桥的顶推滑移施工模拟分析研究,以项目为基础,针对性地进行了过程模拟及要点分析,以图为相似的工程提供借鉴。

With the infrastructure construction of Yunnan province to carry out,in response to the national green highway construction,reduce construction damage to the environment,reduce the risk of high-altitude operations,steel box girder hydraulic top push sliding construction gradually increased. Project the top simulation of an expressway in Yunnan province across the river to push the sliding construction of steel box girder bridge analysis according to the actual situation,based on project,according to the analysis of process simulation and provide reference points in similar engineering.
