Abstract


Jinghe River area is landslide (generalized) disaster-prone areas, and the area is typical loess landslide. With the \Landslides in the study area (generalized) distribution of and control measures, not only conducive to life and property safety of local residents and the economic and social development, but also for national and regional development strategies of great practical significance. This paper studies the following issues: (a) time and space on both sides of the Jinghe River landslide (generalized) distribution and the formation of influencing factors, the results show that the temporal and spatial distribution of landslide and its formation is closely related, and are subject to , the combined effect of external factors affecting the cross, while showing cycle time distribution cycle characteristics, spatial distribution characteristics showed regional differences. (2) in accordance with the Jinghe River ramp structure and the different types of classification, and the structure-prone slopes and type of analysis, the results showed that the degree landslide-prone slopes subject to its original structure type was obvious. (3) for two typical areas Jinghe River landslide formation mechanism and historical evolution of a preliminary study and research, and come to the formation of two types of landslides are subject to differential uplift Weibei Jinghe lateral erosion effects, but the difference is : west riverbank landslide landslide formation mechanism has cut the rear sliding layer rotating basis in the front portion of the slide body prop engine at high speed gravel layer slip and slide structure catechesis and other characteristics; while Tang Village landslide formation mechanism of the slicing deep rear sliding body rotational slide, while squeezing the front slope from the north bank cut Jing Jing River and carrying forward movement towards the north shore and in the rear of the slide body stable without large deformation characteristics. (4) using 2D-Block discrete element numerical simulation software on two typical areas Jinghe River landslide simulation. By tracking the model and the sliding block analysis of simulation results, the model simulation and physical landslide formation and evolution basically. The results showed that the use of two types of loess landslide 2D-Block discrete element numerical simulation software simulation is feasible, while modeling, block division, the selected simulation parameters are suitable. (5) Through the Jinghe River landslide (generalized) the distribution of the characteristics of the formation conditions and the analysis of deformation and failure to follow the principles of governance as a precondition, propose appropriate prevention advice and suggestions. In short, according to local conditions in a comprehensive way in order to take preventive measures.
