节理面的构造特征是鉴别节理力学性质的重要依据。在一些著作中通常把节理面描述为平滑的和粗糙的两种基本类型。前者被认为是剪节理的特征,反映破裂两侧岩块的相对错动;后者则作为张节理的标志,反映两侧节理块只发生垂直破裂面的位移,但是在许多节理面上却发育有非常美观的、好似精雕细刻的羽毛状花纹,对其成因显然不能用前述两种情况简单比拟。这种节理面构造首先受到J.B.Woodworth(1895,1896)的注意并加以描述,此
The structural features of the joint surface is an important basis for identifying the mechanical properties of joints. In some works, joint surfaces are usually described as two basic types of smoothness and roughness. The former is considered to be a feature of shear joints and reflects the relative displacement of rock masses on both sides of the rupture. The latter is used as a marker of Zhang joints, reflecting only the vertical rupture plane displacement of the joint blocks on both sides but developing on many joints There are very beautiful, as if carved feather pattern, its cause can not be clearly compared with the previous two cases. This jointed surface construction was first noted and described by J. B. Woodworth (1895, 1896)
