贵刊1986年第2期刊载了陶振宇先生撰写的“对岩芯饼化的应力分析一文的讨论”(以下简称“讨论文”,)对我们1984年第5期发表的“岩芯饼化的应力分析”一文(以下简称“分析”一文)提出了某些意见,现作出答复并进一步讨论如下。 众所周知,岩石是一种非均质的、不连续的介质,而且处在非常复杂的环境中,受地应力场、温度、地下水等因素的影响,这给研究工作带来很大的困难,人们不得不采用简化的方法,突出某些主要因素,忽略一些次要的方面,以建立某些相应的关系。所以,无论是古典的、还是现代的理论和方法,无不受到某些条件的制约,存在着局限性。 我们在探讨岩芯饼化的破坏机理时,在试验的基础上也作了相应的假定,即“饼化”是由剪切破坏形成的,因而使问题得到简化。这个假定也反映了在某些地质背景下,岩芯饼化的机理,具有一定的代表性,深入研究也有助于对岩芯饼化的认识。
The 2nd issue of your magazine in 1986 contained the “Discussions on the stress analysis of core cakes” written by Mr. Tao Zhenyu (hereinafter referred to as “the discussion paper”). The “Stress Analysis” article (hereinafter referred to as the “Analysis” article) put forward some opinions. The reply is given and further discussion is as follows. As we all know, rock is an inhomogeneous and discontinuous medium, and it is in a very complex environment. It is affected by ground stress field, temperature, groundwater and other factors, which brings great difficulties to research work. People Simplified methods have to be adopted to highlight some of the major factors and to ignore some minor aspects in order to establish certain corresponding relationships. Therefore, both the classical and modern theories and methods are subject to certain conditions and have limitations. When we explored the damage mechanism of core cakes, we also made corresponding assumptions on the basis of experiments. That is, “cake” is formed by shear failure, thus simplifying the problem. This assumption also reflects the mechanism of core cake formation under certain geological backgrounds. It has a certain representativeness, and in-depth research will also help to understand core cakes.
