摘要

考虑了影响尾矿坝安全稳定性的众多因素,利用SLOPE软件建立了尾矿坝安全稳定性简化模型,计算出尾矿坝的稳定性系数,得到了坝尾矿坝库水位与尾矿坝体稳定性之间的关系。计算的坝体安全稳定性系数与实际的安全稳定性系数符合较好,误差均小于0.2%,说明该模型预测坝体的稳定性是非常有效的。利用该计算结果可以方便快捷地预测坝体的安全稳定性,为坝体失稳提前采取有效的安全措施提供了有利参考,避免坝体失稳造成的重大灾害。
Considering many influencing factors of the tailings dam safety and stability, a simplified model of the tailings dam was established by SLOPE software. The safety and stability coefficients of the dam were calculated in the model, in additional; the relationship between the water level and stability of the tailings dam was obtained. The relationship is consistent with the reality. All the errors are lower than 0.2%. It is valid to predict the stability of dam by the model. The current result is significant to predict conveniently the security and stability before falling instability of dam. Effective measures can be taken to avoid the collapse of dam by the results.
