腊八斤大桥
“始终坚持技术研究来源于工程、立足于工程、服务于工程的理念。”
“基于对钢管混凝土材料与结构性能的深入研究,我们不断发现其优良的力学性能,于是拓展了钢管混凝土在其他桥型中的应用。”
牟廷敏开展了“中等跨度钢管混凝土桁梁桥成套技术研究”、“钢管混凝土组合高桥墩技术开发研究”等国家和部省联合攻关科研项目,提出了“钢管混凝土桁梁桥”和“钢管混凝土组合高桥墩”等新结构,为高烈度地震区桥梁建设提供了新选择。
为了突破钢筋混凝土箱型拱桥建设困难、工序较多的技术瓶颈,牟廷敏和他的团队将钢管混凝土技术成果引入其中,从高强材料、简化施工出发,开展了“大跨径钢筋混凝土箱型拱桥成套技术研究”、“基于强劲骨架的特大跨钢筋混凝土拱桥设计施工关键技术研究”等科技攻关,提出了“悬臂浇筑主拱法”、“强劲骨架外包主拱法”等成套新技术,攻克了钢筋混凝土拱桥体系转换较多、工序复杂、施工周期长等难题。
老一辈设计专家们“吃苦耐劳、无私奉献”的敬业品质、“开拓创新、追求卓越”的价值取向、“质量为本、科技领先”的管理理念、“自强不息、止于至善”的精品意识、“求真务实、精益求精”的工匠精神,都是沉淀下来的优良传统和宝贵财富,是值得我们永远传承和弘扬的。
在困难面前,攻破一个个难题是牟廷敏工作职责必需。随着四川高速公路建设深入到藏区、彝区,地形地质条件将更加复杂险峻,对他的工作的挑战也越来越大,但牟廷敏同样有信心将这些新的难题一个个破解,“为四川高速公路建设事业发展奉献我们最大的科技能量。”(中工网记者葛文琦通讯员匡成刚)
