本文借助于思想实验的研究方法,讨论了菱形边上拉剪应力变化特点。得到的结论是两组结构面与自由面夹角越小,结构面上拉应力则越大,岩石越易破坏,破碎范围越大。
In this paper, with the help of the research method of thought experiment, the variation characteristics of tensile shear stress on the edge of diamond are discussed. The conclusion is that the smaller the included angle between the two structural planes and the free surface, the larger the tensile stress on the structural plane, the more susceptible to damage the rock, the greater the scope of the broken.
