摘要： 借助于岩土工程、岩土力学、岩石力学、土木工程等学科,提出了破碎、破碎体(破碎性地层)概念。阐述了这类岩体的破坏方式、破坏的失稳类型。根据热力学定律和微观结构观点,岩体破碎过程实质上是一种内能耗散现象,破碎的发生意味着要耗散一部分能量去产生新的裂纹面。给出了破碎性地层的稳定准则,可用以确定裂纹的稳定状态。当裂纹失稳时,裂纹会向前扩展演化,产生新的裂纹,到一定程度后,将会导致岩体破碎。

Abstract: The concept of disintegration and disintegrated rock mass is put forward in accordance with the practice of geotechnical engineering, geotechnical mechanics, rock mechanics and civil engineering. The failure modes and lost-stabilization types for disintegrated rock mass are discussed. According to thermodynamic principles and from the viewpoint of microscopic struc-ture, the process of rock disintegration is virtually a kind of internal energy dissipation, and the realization of disintegration means that a partial energy is dissipated to produce new cracks.The steady criterion for disintegrated rock mass is proposed.
Key words: disintegration, failure mode, rock mechanics, thermodynamic analysis, criterion, hole damage
