波形钢腹板组合梁桥异步浇筑线形计算及工作面长度分析OA
Linear Calculation and Analysis of Working Face Length of Composite Beam Bridge with Corrugated Steel Webs by Asynchronous-Pouring-Construction Technology
多工作面异步浇筑法作为波形钢腹板组合梁桥的一种高效建造方法,得到了国内多个工程项目的推广应用.基于施工过程中N-1节段顶板、N节段底板、N+1节段波形钢腹板形成的异步工作面,研究了每个工作面的长度参数对施工线形的影响.首先,提出线形简化计算方法,通过推导悬臂前端变形预测公式,建立了工程实例的有限元模型,随后结合现场监测数据,验证了计算公式的正确性;其次,分析N节段底板、N-1节段顶板的工作面浇筑长度分别为3.2、4.8、6.4 m组合时对施工线形…查看全部>>
As an efficient construction method for composite beam bridges with corrugated steel webs(CSWs),the asynchronous pouring method with multiple working faces has been widely promoted and applied in multiple domestic engineering projects.Based on the asynchronous working faces at the roof plate of N-1 section,bottom plate of N-section,and CSWs of N+1 section during the construction process,the influence of length parameters of each work-ing face on the construc…查看全部>>
