Statistical analysis of particle size distribution in barrier dam
摘要
Abstract
Barrier dams are usually induced by earthquakes and rainfall,so it is of practical significance to analyze the material composition of barrier dam to explore the stability of dams and carry out downstream disaster assessment.In this paper,the numerical distribution of particle gradation and the structural difference of dam body in different regions are investigated by statistical analysis.On this basis,through the Analysis of the particle gradation of stable and unstable dams,it is found that the maximum 5%coarse particles significantly affect the stability of the dam,and a particle gradation index DCI is proposed by Principal Component Analysis(PCA)technology.The research results can provide reference for the risk assessment of dams.关键词
