摘 要: 以双剪应力准则与广义双剪应力准则为基础,进一步考虑岩土材料强度性质在偏平面和拉压子午线上不同于金属材料的变化规律,得出适用于描述岩土材料破坏规律的双剪应力多参数准则。同时为计算机处理塑性应变增量的方便,对双剪应力多参数准则进行角点修圆,得出了相应的角隅模型。
关 键 词: 岩土工程;双剪应力;三参数准则;四参数准则;五参数准则;角隅模型

Abstract: This paper is based on double shear stress criterion and generalized double shear stress criterion, and further considered geotechnical material strength properties in partial plane and tension and compression on the different meridians of metal materials. It is concluded that the change rule of geotechnical materials suitable for describing the double shear destruction rule multi-parameter criteria. At the same time, in order to computer processing plastic strain increment of convenient, angular point repair round was applied to double shear stress multi-parameter criterion, and the corresponding corner model was obtained.
Key words: geotechnical engineering; double shear stress; three parameter criterion; four parameter criterion; five parameter criterion; corner model
