跨线桥施工方案比选研究

Research on Comparison and Selection of Construction Plans for Overpass Bridges

针对跨线桥施工中的众多影响因素,分析了各种跨线桥施工技术与施工方案影响因素,通过层次分析法对不同的施工方案进行比选。研究结果表明:支架现浇施工方案是案例项目施工方案中的最优方案,并且在最终成型桥梁中,通过了质量验收规范。这不仅有助于合理优化资源配置,缩短施工工期,还能获取最符合设计工程需求与实际情况的最优方案,减少施工中的风险,促进环境的可持续发展。

In view of the many influencing factors in the construction of the bridge,the paper analyzes the influencing factors of the construction technology and construction scheme of the bridge,and compares the different construction schemes through the analytic hierarchy process.The results show that the cast-in-place construction scheme of the scaffold is the best scheme in the case project construction scheme,and in the final formed bridge,it has passed the quality acceptance specification.This not only helps to rationally optimize the allocation of resources and shorten the construction period,but also can obtain the best scheme that best meets the needs and actual conditions of the design engineering,reduce the risks in the construction and promote the sustainable development of the environment.
