摘要
采用SIGMA/W通过应变控制模拟对某铜矿湖相淤泥在不同含水率的情况下进行极限承载力研究,分别分析了湖相淤泥极限承载力与含水率、孔隙比、压缩模量、凝聚力和内摩擦角之间的关系,得出了适合于湖泥剥离的最优承载力要求,为工程应用提供了可靠的理论依据。
The ultimate load-carrying capacity of lacustrine clay at different water contents was studied by SIGMA/W through strain control simulation in a copper mine.The relationship between the ultimate load-carrying capacity and water content ratio,void ratio,modulus of compression,cohesion and internal friction angle of the lacustrine clay is analyzed.The optimal load-carrying capacity requirements for lacustrine clay stripping are obtained.Research conclusion provide a reliable theoretical basis for engineering applications.
