尾矿坝稳定与否是尾矿库能否安全的关键所在,尾矿坝又是随着生产过程而不断加高的特殊岩土工程体,各种因素处于动态变化过程中,这使得尾矿坝工程的不确定性尤为明显,工程难度较其他类型的边坡工程有增无减。运用FLAC模拟某尾矿坝的筑坝施工过程,分析了再筑坝过程中,逐级加载时上部荷载对原有尾矿坝体安全性能的影响,考虑了由下至上逐步形成重力荷载,最后叠加得到的便是最终内力和变形。为尾矿坝工程建设提供可参考的依据,减少溃坝事故的发生。
Whether the tailings dam is stable or not is the key to the safety of the tailings dam. The tailings dam is a special geotechnical engineering body that is continuously raised with the production process. Various factors are in the process of dynamic change, which makes the tailings Uncertainty is particularly evident in the dam project, the project more difficult than other types of slope engineering. FLAC was used to simulate the dam construction process of a tailings dam. The influence of the upper load on the safety performance of the original tailings dam during the re-dosing process was analyzed. The gravity load was gradually formed from bottom to top, and finally Superimposed is the ultimate internal forces and deformation. It can provide references for the tailings dam construction and reduce the occurrence of dam break.
