Development Of Database Integrated Application Platform Based On Improved Landslide Disaster Scope Model

Landslide is the largest geological disaster in China,which often cause serious casualties and economic losses.In recent years,with the continuous attention to the landslide prevention,the subject of Landslide Motion Prediction after instability has become a research hotspot.Based on the analysis of the existing research in the field of landslide disaster scope,this paper explores the influencing factors related to landslide instability by means of model experiment,and improves the existing landslide disaster scope prediction model.On this basis,the classification standards for landslide prediction are proposed,and the related database application integration platform is developed for the convenience of application.The specific research of this paper is as follows:1.Using the method of model experiment,the parameters of the evaluation model of slope toe landslide are analyzed.Based on the analysis of the model parameters(the volume of landslide mass,the maximum height of slope,the slope angle of the slope sliding source area,the slope angle of the accumulation area and the difference between the two slope angles)by using single factor control method,the height difference of sliding source area is increased to improve the existing model.Through the improved model,the optimization degree of prediction model is given,and a new evaluation model for slope toe landslide is obtained.2.Make statistics on different types of landslides,including slope toe landslides,and summarize the assessment models of landslide disaster scope under different geological conditions in China.On this basis,the application scope and principle basis of different evaluation models are analyzed,and the classification that meets the needs of China's geological disaster prevention and control is given.Through the development of the program,the landslide disaster scope evaluation model is displayed.3.On the basis of the existing evaluation model,further expand the function of landslide disaster scope evaluation.Using the idea of engineering analogy,the database information platform based on spatial prediction of landslide disaster is given to meet the functional requirements of landslide disaster assessment.In addition to the landslide disaster area assessment model,the information platform further conducts pre-processing research on the relevant methods in the numerical simulation software,and forms an application platform of landslide disaster area information,which is composed of engineering analogy method,empirical statistical model and numerical calculation model.This study provides a data processing platform for landslide disaster assessment in engineering practice.Combined with landslide early identification,it can be used to establish landslide monitoring and early warning system in China.
