An Study On Instability Mechanism And Stability Of Bus Station Landside In Yiliang County

Landslide is one type of sudden geological disaster, there are many factors, such asraining, earthquake, engineering program etc. With the increasing of engineering program,this factor has become the main incentive. Moreover landslide usually will bring seriousdamage both on people and economic, even cause broken for geological environment,which had hindered continuous development of local economic. So it is very important forpeople to find out the scientific method to solve landslide.This paper is taking Yiliang bus station as research object; make an analysis ofstability of landslide. This paper is a conclusion based on research and exploration of earth,water, geological structure. We have adopted GeoStudio analysis software to test degree ofstability of landslide, which had supplied scientific reason for managing of landslide, whichcan be applied for decreasing damage caused by landslide.Our main work and conclusions are focused on following:1. We made a systematic research aim at forming of stacked landslide, and adopt thesteps from field study to laboratory experience, then make analysis of stability and havesimulations of data, then make systematic analysis to the whole landslide area.2. Make deep analysis of geological character which based on research of basicresearch, then make analysis for stability. After onsite monitoring for surface crack andshifts, we find the toe of slope were broken is the most important factor.3. According to the identified condition, we adopt fixed method to make analysis forstability, the results show that landslide is stable when it is in natural state, but after digging,it is under unstable state, and cracks are appearing.4. We use GeoStudio software to make a data simulation, and find out the distortioncharacter.5. According to the stability analysis, we know that the slide is unstable after digging,so we must adopt measures such as slide pile, anti-earth wall, drainage etc to solve.
