摘要
Abstract
Taking the loess bedrock landslide in Lantian County as an example,its basic characteristics and deformation characteristics under rainfall were obtained through field investigation.The deformation evolution law of loess bedrock landslide under rainfall is revealed by field monitoring.The results show that the loess bedrock landslide in the Alfalfa Gully under the action of rainfall shows three deformation stages:initial stage,constant speed stage and acceleration stage.The landslide deformation time curve shows the characteristics of'step type',and shows continuous'creep type micro change'in the macro deformation interval.The failure mode is six stages:original slope-fold line collapse-crack deepening-arc crack-sliding surface basic penetration-overall sliding failure.The research can be of practical significance for disaster prevention and mitigation and early warning theory of loess bedrock landslide.关键词
