摘要
基于塑性力学和极限分析理论,研究了岩土体的体积塑性耗散功率和面积塑性耗散功率,并以平动性滑坡为例,给出了滑坡体塑性耗散功率和安全因子的计算方法.
Based on plastic mechanics and limit analysis theorem, the power of plastic dissipation that is dissipated in any kinematically admissible failure mechanism is studied. As an example, the method calculating the plastic dissipation power and safety factor of translation landslides is given.
