斜坡形、冲沟与滑坡之间演化关系初探

Preliminary Analysis of Evolution among Slope Deformation,Gully and Landslides

以地球系统科学的整体观、系统观为指导思想,将斜坡变形、冲沟及滑坡放在斜坡系统的演化中来研究。在进行陕西陇县滑坡灾害调查研究基础上,对斜坡变形的规律,斜坡变形与滑坡之间的本质区别,斜坡变形与冲沟发育的关系,滑坡发育与冲沟演化的关系分别进行了研究,在此基础上探讨了斜坡变形、冲沟及滑坡三者之间的演化关系。

Under the instruction of Earth System Science（ESS）,based on field research,indoor examination analysis and FEM numerical simulative calculation,the authors use multidisciplinary theories and methods,focusing on mutual evolution among slope deformation,gully and landslides.Such preliminary results and new principal progress are made as follows： the gully has extinct control on slope deformation;on the other hand,slope deformation affects growth of subgullies.Two sides have complicated coupling relation.Slope deformation and growth of gully change physiognomy of slope at a large extent,making slope unstable and causing landslides.
