施工方案的确定在满足安全、环保、质量、工期目标的前提下,确保技术上的可行性,同时根据工、料、机等生产要素情况,通过多方案比选和综合技术经济分析比较后,进行方案的不断优化,最终确定合理方案指导实施,从而达到项目的最佳利益。先简支后连续桥梁梁板安装施工方法通常为架桥机和吊车架设两种方法,本文结合邢衡高速新周大桥箱梁架设方案的比选,详细分析方案的比选和优化。
On the premise of meeting the objectives of safety, environmental protection, quality and construction period, the construction plan is to ensure the technical feasibility. At the same time, according to the comparison of production, materials, machine and other factors of production, through the comparison and analysis of multiple plans and comprehensive technical and economic analysis, To optimize the program, and ultimately determine the appropriate program to guide the implementation, so as to achieve the best interests of the project. First, the construction method of continuous beam plate installation after simply supported support is usually two methods of erecting machine and erecting crane. Based on the comparison and selection of box girder erection scheme of Xin-Heng Bridge in Xing-Heng Expressway, the scheme selection and optimization are analyzed in detail.
