结构面力学性质的鉴定,是地质力学方法的基础性工作,是正确地进行构造体系分析,从而指导生产实践的必要前提和关键。根据以往的经验,对于性质单一的结构面(单性结构面),一般比较容易识别,它们的基本构造特征也是大家所熟悉的。然而在许多场合,如扭动构造长期发展地区、不同构造体系复合地段,结构面的力学性质往往比较复杂,常显示有两种以上不同性质的特点。在经历不同方式构造变动的多体系复合地段,这种现
Identification of the mechanical properties of the structural plane is the basic work of the geomechanical method, which is the necessary prerequisite and key to correctly analyze the structural system and guide the production practice. According to past experience, it is generally easy to identify the single structural planes (unisexual structure planes) whose basic structural features are also familiar to all. However, in many occasions, such as twisting the construction of long-term development zones and complex structural systems, the mechanical properties of structural planes are often complicated and often show two or more different characteristics. This is the case in multi-system compound lots that have undergone structural changes in different ways
