| 摘 要： | 阶状构造是地壳岩石断裂面上的一种小型构造，它反映地壳岩石在断裂形成时期的应力状态和两盘运动趋势，提出了一类阶状构造的力学解析方法，表明阶状构造形成条件，主断面与阶面形成的应力状态，结构面力学性质鉴定和断面相互错动趋势判别等等，由计算自动得出。

| Abstract: | Step structures are a kind of minor ones on fractural plane in the earth crust, reflecting the stress states for formation of fractures and the potential of relative movement between two walls of a fracture. The authors suggest a mechanical analytical method for the kind of step structures, the condition for formation of step structures and the limiting stress states in the main fractural plane and in step planes, the determinations of mechanical properties of structural planes and of potentiality in mutual shear automatically through calculation. |

| Keywords: | step structures reversed step mechanical properties of structural plane structural analysis |
