| Landslide is a common geological disaster.In recent years,with the aggravation of human engineering activities and the deterioration of climatic conditions,every year people have lost their lives in landslides,and the economic losses caused by hundreds of millions.The landslide is a serious threat to national property and People 's life safety.With the country put forward to build a harmonious society and promote the "people-oriented" call,China has increased year by year on the geological disaster research,governance.Landslide exploration work as a preventive work of the preparatory work is particularly important,reasonable and effective exploration work,a direct impact on the decision-making project.The scope of the study area is mainly Xishan landslide H1-2 area,according to field exploration,the disaster area of the main threat to the West and the county's Yangshui River left bank area and the west slope of the residents,threatening population and property huge threat within the scope There are about 18 households,and the total population of about 3,000 people,and the other 15 acres of farmland,the county a large number of social public resources,threatening assets at least 500 million yuan.The shape,the boundary,the range,the size,the material structure,the deformation and failure characteristics,etc.)and the hazard object of the H1-2 landslide are analyzed by means of comprehensive exploration methods and methods to analyze the geological environment conditions of the study area Factors,formation mechanism and failure mode,etc.;evaluate the stability of the situation,analysis of the development trend of H1-2 landslide;for the prevention and control of engineering design to provide a reliable geological basis.The results show that the H1-2 landslide is in a stable and stable state under the self-weight condition.In the unfavorable condition,it is under-stable and unstable.The X1 unstable slope section is in a steady state under heavy duty conditions.And the earthquake is not stable-unstable state.The comprehensive evaluation analysis shows that the stability of the H1-2 landslide in the Xishan landslide survey is poor and the stability of the X1 is poor-the stability is poor.Considering the geological structure and stability of the H1-2 landslide,it is suggested to adopt the anti-slide pile support + surface drainage + fence project to carry out comprehensive prevention and control measures. |
