构造体系概念是地质力学的核心,组成构造体系的基本单元—结构面,则是它的基础概念。正确理解和运用结构面概念,则是地质力学分析的基础。研究结构面的几何和力学性质及其在空间的展布规律,其主要目的在于认识和建立构造体系,并由此推导其构造应力场以及导致该构造型式的动力作用方式,进而作出成因上的解释。 结构面概念是根据地质力学的研究方法特点提出的,有它特定的几何、力学含义,并已被广泛地应用于地质构造的力学分析。但在涉及有关结构面概念的众多地质文献和教科书中,对它的理解却不都是一致的;在运用它作构造应力场分析(特别是平面应力场分析)
The concept of tectonic system is the core of geomechanics. The basic unit of structure system - structural plane is its basic concept. Correct understanding and application of the concept of structural plane is the basis of geomechanical analysis. Studying the geometrical and mechanical properties of the structural plane and its distribution in space, its main purpose is to recognize and establish the tectonic system and derive its tectonic stress field and the dynamic mode of action that leads to the structural type, and then make the genesis Explanation. The concept of structural plane is based on the characteristics of geological mechanics research method, has its specific geometric and mechanical meaning, and has been widely used in the mechanical analysis of geological structure. However, many geological documents and textbooks concerning the concept of structural plane do not all share the same understanding. When it is used to construct the stress field analysis (especially the plane stress field analysis)
