| 摘 要： | 由双剪应力屈服准则（１９６１）和双剪强度理论（１９８３）为基础提出并推导了一个新的双剪正交和非正交滑移场理论。现有的在机械工程、土木工程和岩土工程应用的各种滑移线场理论论均可作为双剪滑移线场理论的特例。研究结果与作者以前取得的实验结果相比较，两者甚为吻合。

| Abstract: | The twin shear strength theory of Yu Maohong is generalized to the theory of slip line field in thispaper.The twin shear strength theory includes the twin shear stress yield criterion proposed by Yu in1961 and the generalized twin shear theory proposed by Yu in 1983.Based on the twin shear strengththeory,a new twin shear orthogonal and non-orthogonal slip line theory are proposed and introduced,The well-known sllp line theories used in the mechanical,civil and geotechnical engineering are thespecial cases of this twin shear non-orthogonal slip line theory,The comparisons between the twinshear slip line theory and the authors'experimental data show a satisfactory agreement. |
