变分法在尾矿坝稳定性分析中的应用研究
|
摘要
分析研究了变分法在尾矿坝稳定性分析中的应用,利用研究开发的尾矿坝二维变分分析程序对不同工况的尾矿坝进行了稳定性分析,并与极限平衡分析法进行对比,结果表明:分析结果比较接近,采用对数螺旋滑动面进行变分分析更合乎实际。
The application of variation calculus in stability analysis of tailing dam was studied. The stability analysis of the tailing dam in different working conditions was carried out using the studied and developed 2-D variational analysis program of the tailing dam, and comparative analysis with limit equilibrium analysis method was made. The result shows that both analysis results are close,and adopting logarithmic spiral sliding surface for variational analysis is more practical.
