尾矿库漫顶溃坝模型研究
Research on tailings dam break due to overtopping
摘要
Abstract
To analyze the tailings dam failure process due to overtopping, a physical model of the tailings dam was conducted. The breach process, the dam failure flood process and inundated height of flood in downstream were observed by using topography measuring equipment for 3D, surface flow distribution mea⁃suring equipment and ultrasonic wave gauges. The collapse volume of breach and outflow discharge fluctuat⁃ed due to the block collapse. The overtopping flow included general sediment-laden flow, high sedi⁃ment-laden flow and high bed load transport. Based on this physical motion graphics, a physical-based model is established for calculating the flood process using the non-equilibrium sediment transposition and a conceptual model for the process of lateral erosion. The model is verified using the physical model re⁃sults. The agreements between calculated and measured data show the applicability of the proposed model.关键词
