中文摘要: 为保证排洪系统安全、可靠运行,本文通过制作尾矿库排洪系统水工模型,模拟1#~3#排水竖井逐级运行方式下,排水竖井的溢流特性及其他工程水力学问题,研究排洪系统在最不利运行工况下主、支洞交汇区泄洪隧洞内流态、壅高及压力分布规律,检验库内排洪系统和库外主泄洪隧洞是否存在空化、气蚀等现象,校核各泄洪系统的泄流能力,可为尾矿库或类似工程设计和应用提供参考。
Abstract:In this paper, in order to ensure that the flood discharge system works safely and reliably, the hydraulic model of the flood discharge system of tailings reservoir was made to simulate the overflow behavior and other engineering hydraulic problems of the drainage shaft under the stepwise operating mode of 1#—3# drainage shaft. Flow state, run up height and pressure distribution law of the flood discharge system in flood discharge tunnel of confluence area of main and branch tunnels under the most unfavorable operating conditions were studied. Whether there were cavitation in the flood discharge system inside the reservoir and the main flood discharge tunnel outside the reservoir were tested, andthe discharge capacity of each flood discharge system was checked. This work can provide reference for the design and application of tailings reservoir or similar projects.
