摘要:
通过对有限元强度折减法的理论研究，将此法应用到尾矿坝的静力稳定计算中。采用有限元强度折减法和极限平衡法对某尾矿坝进行了坝坡抗滑稳定安全系数的计算，计算结果表明，在应用有限元强度折减法时，采用不同的D-P准则计算出的滑动面基本相同且与传统方法相近，其中D-P3准则计算的安全系数更加接近瑞典圆弧法。因此应用有限元强度折减法求解尾矿坝静力稳定安全系数是可行的，同时说明有限元法可以较好的模拟实际工程中的复杂几何断面形状和材料非线性等问题。
Abstract:
From the study of shear strength reduction finite element methods (SSRFEM), the static stability analysis of tailing dam was carried out by this method. The different DP criterion was used to calculate the antiskiding stability safety factor of dam slope by the SSRFEM and traditional limit equilibrium methods. The results showed that the failure surfaces under different DP criterion were closed to classical method, and the safety factor from DP3 criterion was much more closed to the one which was got from the Fellenius method. So, it is feasible to calculate the antiskiding stability safety factor of tailing dam by the SSRFEM. Also, it indicates that the finite element method is suitable to simulate the complex section and nonlinear material in practical engineering.
