某铀尾矿库地震动力稳定性分析

Seismic Dynamic Stability Analysis of One Uranium Tailings Pond

地震是影响铀尾矿库稳定性的重要因素之一。为研究铀尾矿库在地震动作用下的动力特性,以某铀尾矿库为例,对尾矿库在设计地震条件下的动力反应进行了模拟计算,得到地震过程中尾矿坝体应力、加速度反应、变形、液化和动力稳定等计算结果。研究表明,该尾矿库在设计地震条件下总体表现良好,坝体稳定性可以得到保障。

Earthquake is an important factor which influences the stability of uranium tailings pond. In order to study the dynamic characteristics of uranium tailings pond, taking one uranium tailings pond as example, seismic reaction of tailings pond was simulated and calculated under design seismic condition, and calculated results of tailings pond dam stress, acceleration reaction, deformation, liquefaction and dynamic stability are obtained. Study indicates that the uranium tailings pond is in good condition when it suffers designed seismic condition, and the overall stability of the dam is guaranteed.
