Modular composite bridges for winter roads

北部偏远社区依靠冰路提供一种可行的方式，将材料和其他物资运送到其他难以到达的地区。冰路可在短时间内通行，需要可靠且易于建造的临时桥梁。目前正在使用的桥梁是“机械”型桥梁。这些桥梁由于其重量而难以运输，安装劳动密集型，并且在季节结束时不容易拆除。马尼托巴基础设施和交通（麻省理工学院）已经确定了一个轻量级的，单跨，可移动的桥梁，更容易运输，安装和删除在赛季结束的需要。马尼托巴大学和结构复合材料技术公司之间的这种新的合作伙伴关系将研究使用轻木芯和纤维增强（FRP）外壳建造的复合材料单跨桥梁的可行性。复合强化解决方案被认为是以合理的成本满足性能要求的最佳方法。复合材料设计可以提供耐腐蚀性和非现场预组装，除了比现有的同等钢和木材设计减轻重量的好处。

Remote communities of the North rely on ice roads to offer a feasible way to deliver materials and other supplies to otherwise hard to reach areas. Ice roads are accessible for short periods of time and require temporary bridges that are reliable and easy to construct. The bridges currently being used are "Mechano" type bridges. These bridges are difficult to transport due to their weight, are labour intensive to install and are not easily removed at the end of the season. Manitoba Infrastructure and Transportation (MIT) has identified a need for lightweight, single span, removable bridges that are easier to transport, install and remove at the end of the season. This new partnership between the University of Manitoba and Structural Composite Technologies will investigate the feasibility of using composite single span bridges constructed using a balsa wood core and fibre-reinforced (FRP) shell. A composite intensive solution is believed to be the best approach to meet the performance requirements at a reasonable cost. A composite design can offer corrosion resistance and offsite pre-assembly, in addition to the benefit of reduced weight over existing equivalent steel and wood designs.
