岩体结构类型的划分方案已提过许多种,主要划分原则是岩体破碎程度。谷德振教授在一九七七年曾提出:破碎带应作为一种岩体结构单元。他已将“板”作为一种薄层状结构从一般的层状结构中独立出来。之后,孙广忠等在一九八四年第二届全国工程地质大会上正式提出了“板裂”结构的新概念(同期,他还在文献[3]中谈及对劈理带用板裂力学模型进行研究的问题),引起工程地质界和岩体力学工作者的很大兴趣。 岩体结构分类的主要目标是作出比较符合实际的岩体稳定评价,使工程设计臻于经济合理。显然,认识和划定岩体的“板裂”结构,采用特定的力学模型,则有助于针对性地解决具体的工程地质问题。
There are many types of classification schemes for rock masses, and the main principle is the degree of rock fragmentation. Professor Gu Dezhen proposed in 1977 that the fracture zone should be a rock structural unit. He has separated the “plate” from a general layered structure as a thin layer structure. Afterwards, Sun Guangzhong et al. formally proposed a new concept of “plate cracking” structure in the Second National Conference on Engineering Geology in 1984. (In the same period, he also talked about the use of plate cracking mechanics in descriptive tapes in the literature [3]. The problem of the model’s research has aroused great interest in engineering and rock mechanics. The main objective of the classification of rock mass structure is to make a more realistic evaluation of the stability of the rock mass, making the engineering design less economically sound. Obviously, understanding and delineating the “plate cracking” structure of rock masses and adopting specific mechanical models will help to solve specific engineering geology problems.
