摘　　要：根据工程地质习惯,以自然方向为总体坐标系的轴向,给出了对应的结构面矢量描述。研究了取样窗与结构面的相交关系,在取样窗上建立局部坐标架,推出结构面迹线矢量在局部坐标架中的分量和两类坐标架下的结构面矢量变换群;根据变换群的关系和性质,由结构面迹线与测试窗内勘探线的夹角反算出结构面的产状参数,并以最小二乘方法处理。本方法要求现场测试数据少,操作简单、迅速,便于工程应用。According to the manner of engineering geology, the texture plane is described with vector in the natural coordinate system. The intersecting relation of the sampling windows with the texture plane is studied. The local coordinate system is set up on sampling windows and the transition group of the vectors describing texture plane in two kinds of coordinate systems is deduced. The occurrence parameters of texture plane are back calculated from the intersection angles of the sampling line and texture plane traces in the sampling windows on the basis of the relation and peculiarity of group by least square method. This method requires a few site data and is easy to operate and simple to be applied to engineering practice.
