Load, pressure, rubble pile geometry and video data from model-scale tests on shallow water ice-structure interaction

The data is obtained from model-scale experiments on shallow water ice-structure interaction. During the conducted experiments, a ten-meter wide initially intact ice sheet was pushed against a sloping structure of the same width. As the ice failed against the structure, a grounded rubble pile accumulated in front of it. The structure consisted of ten identical one-meter-wide segments and the horizontal load on each of these segments was measured independently with load cells. These measurements are presented as load-time datasets. The horizontal load acting on the false bottom was measured with load cells and are also presented as load-time datasets. Furthermore, the ice pressure on two of the segments was measured with tactile sensors. These pressure measurements are presented as array-based pressure-time datasets. Video footage filmed from two different video angles is included in the data. In addition, the coordinates of the rubble pile geometries at the end of each experiment are published. The data includes the top and side rubble pile geometries. In total, seven experiments were conducted. The data can be used by researchers, engineers and designers who work with ice structure interaction related issues in order to, for instance, optimize the design of offshore structures, improve ice load predictions or develop future experiments and simulations. A full description of the experimental set-up and the published data is submitted to the journal Data in Brief.

本数据集源自浅海冰-结构相互作用（shallow water ice-structure interaction）的模型尺度试验。试验过程中，将一块初始完整、宽度为10米的冰盖推挤向同宽的倾斜结构物。当冰体与结构物发生破坏时，结构物前方会堆积起一处坐底碎石堆。该结构物由10个宽度均为1米的相同分段组成，每个分段所受的水平荷载均通过测力传感器（load cells）独立测得，相关测量结果以荷载-时间数据集形式呈现。此外，假底所受的水平荷载同样通过测力传感器测得，亦以荷载-时间数据集形式发布。另有2个分段的冰压力通过触觉传感器（tactile sensors）采集，此类压力测量结果以基于数组的压力-时间数据集形式呈现。数据集包含两个不同拍摄角度的视频影像。此外，还公开了每次试验结束时碎石堆几何形态的坐标数据，涵盖顶部与侧面的碎石堆几何信息。本次试验共计开展7组。该数据集可供从事冰-结构相互作用相关研究的科研人员、工程师及设计师使用，例如用于优化近海结构物设计、提升冰荷载预测精度，或开展后续试验与仿真研究。试验装置与公开数据集的完整说明已投稿至《数据简报（Data in Brief）》期刊。
