| 英文简介 | The study of stability assessment for landslide dam is the basis and the key of the study of risk assessment and outburst of landslide dam. At present, there are many indexs and methods on stability assessment for landslide dam, but the study of stability assessment for landslide dam is scarce based on the coupled analysis of controlling factors, dynamic process and the mechanism of outburst of landslide dam. This applied project analyze dominant factors and coupling relation by composition-structure and hydrology factors based on on the collected data and field investigations for typical barrier dams and statistical analysis of the causes. The evaluation index will be established based on the above analysis. This applied project will study anti erosion properties of barrier dam and outburst process of barrier dam by simulation experiment of overtopping outburst. The stability assessment model of landslide dam will be established based on the coupling of composition-structure and hydrology factors. Finally, Evaluation model will be verified by cases, and the error and reliability of model will be analyzed. The research work will promote studying of stability assessment for barrier dam. Meanwhile, the research work aslo provides scientific and technological support and services for emergency treatment, disaster prevention engineering, scientific and rational utilization of the landslide-dam lake, and has some theoretical and engineering applications. |
