【摘要】 在查明御驾泉尾矿坝工程地质条件的基础上,采用极限平衡法和快速拉格朗日法计算了坝体标高334 m时在正常运行、洪水运行和特殊运行工况下的稳定系数。结果表明坝体是安全的,但是在特殊运行(地震条件)工况下的稳定系数并不高,仅为1.06,所以需要注意防范尾矿坝在特殊运行工况下发生坝体失稳事件。更多还原

【Abstract】 Based on the investigation of the Engineering Geological Conditions,the stability coefficient of the Yujiaquan tailing dam when dam body in 334 m under normal situation,flood situation and special situation is respectively calculated by limit equilibrium method and Fast Lagrangian Analysis of Continua method(FLAC).The result indicated that the tailing dam was safe in these situation,but the stability coefficient in special situation was only 1.06,just satisfy the requirement of 1.05,therefore,it should pay more attention to the tailing dam stability in special situation(earthquake).更多还原
