Abstract:In order to ensure the safety of life and property of residents in the landslide area, based on the geological conditions of the landslide, the stability of the landslide is studied by using the transfer coefficient method and other methods, and the appropriate landslide prevention and control schemes are screened. The support vector machine is used to predict the deformation after landslide prevention, and the prediction results are used to evaluate the landslide prevention and control effect. The results show that: 1) The qualitative evaluation results of landslide stability have good consistency with the quantitative evaluation results. Comprehensive evaluation shows that the stability of landslides is generally unstable-basically stable, especially under heavy rain conditions, where the risk of landslide instability is high; 2) After the screening of landslide prevention and control schemes, it is concluded that scheme 1 “anti-slide pile + drainage” has the best applicability, and its applicability level is level 4, which is better than the other two types of prevention and control schemes; 3) Through the analysis of the deformation monitoring results of the anti-slide pile after the implementation of landslide prevention and control, it can be seen that the deformation of the anti-slide pile has tended to converge, and the final predicted value range is 24.45~27.82 mm , which is always within the range of deformation control limit, which fully shows that the landslide prevention and control measures are reasonable and effective, and the expected prevention and control purpose has been achieved.
