| 摘 要： | 结构面对于黑方台台塬斜坡变形破坏的影响研究成果较多,但以单方面研究为主,较少进行系统研究,因此通过对黑方台台塬结构面类型及其组合特征以及斜坡变形破坏类型和特征的分析可知:研究区结构面类型主要包括节理裂隙、层面、接触面、断层和临空面,结构面组合类型分2大类8小类,各类型具有自身的结构特征和分布特征;结构面及其组合对黑方台台塬斜坡变形破坏类型选择和空间分布选择控制效应明显,特别是对滑坡类型选择和空间分布的影响。

| Abstract: | The structural plane effect on the deformation and failure of the Heifangtai tableland slope has been well studied; however, such studies mainly focus on a single side, and only few systematic studies have been conducted. Therefore, based on the analysis of the structural plane types and the combination characteristics, the deformation and failure types, and the characteristics of the slope, in this work, it was found that the structural surface types in the study area mainly include joint fissures, layers, interfaces, faults, and free face; the combination types of structural planes are divided into two classes and eight subclasses, and each type has its own structural characteristics and distribution characteristics. The slope deformation and failure types and the spatial distribution selection of Heifangtai tableland slopes are significantly affected by the structural planes and their combination. |
