This research will investigate soil as a reinforcing agent for ice. Ice has been used on many occasions as an engineering construction mater, especially recently as a means of constructing offshore drilling platforms, roads, and airstrips in the Arctic. These constructions could be improved if a suitable reinforcing agent could be incorporated into the ice. First, the material properties of the reinforced ice could be improved over those of natural ice. Second, construction time and costs could be significantly reduced. The work will investigate the use of various alluvia (sands, silts and gravel) as reinforcing agents in ice. Bending tests of both large and small beams will be performed as will compression tests at a controlled strainrate and temperature.

这项研究将研究土壤作为冰的加固剂。 冰已被多次用作工程建设材料，特别是最近作为在北极建造海上钻井平台、道路和飞机跑道的手段。 如果可以在冰中加入合适的增强剂，则可以改进这些结构。 首先，强化冰的材料特性比天然冰有所改善。 其次，可以显着减少施工时间和成本。 这项工作将研究使用各种冲积物（沙子、淤泥和砾石）作为冰中的加固剂。 将进行大梁和小梁的弯曲测试以及受控应变率和温度下的压缩测试。
