摘要
随着上游法尾矿水力冲填筑坝的不断加高,库内水位持续上升,逐步形成高势能尾矿坝。高势能尾矿坝体的物理力学性质指标是否因为坝体的加高而发生变化是需要关注的重点问题,因为物理力学性质指标是分析坝体稳定性的关键参数和基础依据。
With the continuous heightening of the upstream tailings hydraulic fill dam,the water level in the reservoir continues to rise,and a high potential tailings dam is gradually formed.Whether the physical and mechanical property index of high potential tailings dam body changes due to the heightening of the dam body is a key issue that needs attention,because the physical and mechanical property index is the key parameter and basic basis for analyzing the stability of the dam body.
