摘要
首先采用极限平衡法对齐鲁石化热电厂粉煤灰贮灰坝在正常水位和洪水位下的稳定性进行了计算,结果表明坝体稳定性满足相关规范要求,但安全储备偏低。考虑到稳定与变形的关系,采用FLAC程序对坝体稳定性进行分析,得到了可能滑动面的位置和稳定性系数,计算结果与极限平衡法计算结果基本一致。
The factor of stability under of the normal and the flood water level condition of the fly ash tailing dam in the SINOPEC Qilu Co.power plant is calculated by the limit equilibrium method,and the result indicates that the dam is safe,but the safety repertory is low.Considering the relation between the stability and the deformation,the stability of the dam is calculated by FLAC program,and the result by the 2 methods were identical essentially.
