某尾矿库防排洪能力与稳定性分析

Analysis of Flood Prevention Capacity and Stability of a Tailings Dam

尾砂综合利用在助力国家“碳中和、碳达峰”目标实现中扮演重要的角色。本文以某尾矿库作为研究背景,采用现场调查、理论分析和数值模拟等方法对尾矿库防排洪能力与稳定性计算分析技术进行研究,针对尾矿库特定的运行工况下计算尾矿库的排洪能力、渗流场、浸润线,最后评估现状条件下坝坡稳定最不利断面的安全风险。

The comprehensive utilization of tailings sand plays a crucial role in achieving the nation's'carbon neutrality and peak carbon'goals.This paper takes a certain tailings dam as the research background and studies the flood prevention capacity and stability analysis technology of the tailings dam using methods such as on-site investigation,theoretical analysis,and numerical simulation.The flood discharge capacity,seepage field,and saturation line of the tailings dam under specific operating conditions are calculated.Finally,safety risks of the dam slope's most unfavorable section under current conditions are assessed.
