Huangtupo Landslide Stability and Geological Environment of the New Relocation Site in Badong City

To ensure the geological security for the development of urban planning of facility-sliding strata of Badong Formation in the Three Gorges reservoir area, we discuss the geological environment development and protection issues in abnormal slope areas by means of system analysis and analogy. Loess landslide in Badong City is a super complex deformable body formed by multi-stages, and systematic analysis indicates that under the condition of the operation of Three Gorges reservoir, the loess landslide is nearly in whole stability except the front which can be put to restrictive use.So part of relocation is necessary and appropriate. Generally speaking, the new site area and the loess landslide share similar geological environment, belonging to the slope geological environment of the Three Gorges reservoir area characterized by facility-sliding strata of Badong Formation and consequent slope structure. The development of a large number of influential landslides reveals a more vulnerable side of the geological environment, and as a result it can only be subject to restrictive use. Strengthening the construction of geological disaster prevention system and risk management can control the risk level of the planning and development in allowed geologically secure conditions.
