尾矿坝坝体稳定分析因尾矿材料与土的性质不同而使其研究具有特殊性。AD INA有限元计算软件在分析计算岩土边坡稳定问题上有其独特优势,比如结构的非线性分析、流固耦合计算等。文中基于AD INA软件,应用强度折减有限元法对尾矿坝坝体稳定进行了计算分析,得到坝体现状的塑性区分布及抗滑稳定安全系数,计算结果在软件中得到直观显示。工程实例表明,将强度折减有限元法应用于尾矿坝的稳定计算中,能有效地反映尾矿坝稳定性情况。
Tailings dam stability analysis of tailings due to the nature of different materials and soil to make its research has particularity. AD INA finite element calculation software has its unique advantages in analyzing and calculating the slope stability of rock and soil, such as nonlinear analysis of structure, fluid-solid coupling calculation and so on. Based on AD INA software, the strength reduction finite element method is used to calculate and analyze the stability of tailings dam body, and the plastic zone distribution and anti-skid stability safety factor of dam body are obtained. The calculation results are displayed in software. The engineering examples show that applying the strength reduction FEM to the stability calculation of tailing dam can effectively reflect the stability of tailings dam.
