摘要
On the basis of the investigation, it is suggested that the regional fault systems and its activities are essential factors for the development of geological hazards, which can be demonstrated by the following geological facts from the western Qinling: 1) the geological hazards generally developed along the faults as a zone or group, which often determines the intensity and spatial distribution of geological hazards; 2) the fault fractue zone and rapture zone or rock damage near faults during multiple episode deformation, can provide structural slide faces for landslide mass and debris substance for mud-debris flow; and 3) the fault activities, especially earthquake activity of faults are the important induced factor for geological hazards. Therefore in studying rock fall and collapse, landslide and mud-debris flow, the authors put them under the regional geological background, especially regional fault framework, fault zone structural features and fault activities, to understand its development.
