Abstract

Ice-based construction materials used in cold climate regions, including the Arctic, as well as ice itself, exhibit low strength characteristics, which requires constant monitoring of structures created with the use of such materials. In this work, the deformation of samples of unreinforced and basalt-roving reinforced ice is studied and the features of loading and destruction of reinforced ice and unreinforced ice are compared. The unidirectional reinforcement of the ice results in a twofold increase in the strength limit and almost threefold increase in the relative axial deformation before the bending-induced fracture the sample. The possibility of using fiber-optic sensors based on the Bragg grating as monitors of ice deformation is shown. By the example of testing samples for three-point bending, we demonstrate the prospects of the proposed approach to study the deformation of materials based on reinforced and unreinforced ice under external mechanical influence using integrated fiber-optic sensors.

使用集成的光纤传感器研究冰复合材料的变形

摘要

在包括北极在内的寒冷气候地区使用的基于冰的建筑材料以及冰本身均显示出低强度特性，这需要对使用此类材料创建的结构进行持续监控。在这项工作中，研究了未强化和玄武岩粗化强化冰样品的变形，并比较了强化冰和未强化冰的载荷和破坏特征。冰的单向强化会导致强度极限增加两倍，而在弯曲引起的样品断裂之前，相对轴向变形几乎增加三倍。显示了使用基于布拉格光栅的光纤传感器作为冰变形监测器的可能性。以测试样品的三点弯曲为例，
