冻融条件下粘性土堤溃决测点水力要素变化数据集（2018-2021）

本数据集在天津大学水利工程仿真与安全国家重点实验室的弯道水槽中完成，该实验旨在通过测量并分析冻融条件下粘性土堤溃决过程中溃口形态和溃决区域的水力要素变化规律，探究堤防的溃决机理。该数据集包括溃口横向宽度和垂向深度，堤前、堤后、巴歇尔槽水位，巴歇尔槽处流量，测点流速包含x、y、z方向的分流速。This dataset was collected in a curved flume at the State Key Laboratory of Hydraulic Engineering Simulation and Safety, Tianjin University. This experiment was designed to explore the failure mechanism of cohesive soil embankments by measuring and analyzing the variation patterns of breach morphology and hydraulic parameters within the breach zone during the failure process under freeze-thaw conditions. The dataset includes the transverse width and vertical depth of the breach, water levels at the upstream and downstream sides of the embankment and at the Parshall flume, flow discharge at the Parshall flume, as well as three-dimensional flow velocities at measurement points, namely the velocity components in the x, y, and z directions.
