【摘要】 <正>地质构造形态的分析,本质上是地质线（线状构造）、地质面（面状构造）在空间几何关系的研究。产生各种构造形态的主应力轴方位,也可依据有关的线状、面状构造的空间几何关系确定出来。因此,运用数学原理进行地质构造分析是完全必要和可能的。更多还原

【Abstract】 Principles of analysing vectors are applied to establishing several basic calculation formulas commonly used in analyses of geological structures. There are following formulas: the angle between line and line, or between plane and plane, two lines lying in a common plane, pitch, bisector-plane, bisector-line, line of displacement orientation, planar and linear structures revolving about an axis, etc. All kinds of basic data necessary to analysing geologic structures, by using these formulas, can be calculated quickly and simply with a small calculatot. The data may be tested and verified with stereographic projection solutions.更多还原
