摘要
市政道路工程是维持整个城市持续发展的经脉,是市民日常生产和生活正常进行的重要保障。路基作为道路承载的主体,其设计的科学合理性与施工质量的好坏将决定整条道路的使用寿命,关系到城市的经济发展和城市活动的进行。路基填料的选择、路基的填土与压实、路基的排水、路基的防护是市政道路建设的关键环节,也是道路常见问题的源头。论文结合多年道路工程设计与现场经验,对市政道路路基的设计优化措施进行了分析、探讨,以期为我国市政道路建设中的路基设计与施工作业提供有益的理论支持和实践引导。
Now long-cantilevered steel canopy is applied in engineering, so in this paper the canopy is categorized. The merits and demerits is given and the load, loadcase, action are summarized, furthermore, the controlling factors for bars and the details of key joints are suggested. At last, based on above, a series of 6m long-cantilevered steel canopy are analyzed, in addition, the data of result and the section of every bars are investigated and all these data are analyzed and compared.
