Hazard Degree Assessment on Site-Specific Debris Flows in Dongchuan of Yunnan Province
摘要
Abstract
Scale and frequency of debris flow are two essential parameters of hazard degree, and therefore are the two primary factors of the hazard assessment. So, composite hazard degree are expressed by scale hazard degree and frequency hazard degree. Base on the correlation analysis of the debris flow gullies in Dongchuan, Yunnan, minor risk factor significantly correlated with scale and frequency of debris flows are got, and a linear relationship between major factors and minor and factors related are discovered. By using multi-variant linear-regression analysis, weights of minor hazard factors are calculated and a hazard degree assessment model for site-specific debris flow is established. Hazard degree of every debris flow gully is calculated by the model, and hazard assessment on the debris flows are done and later proved to be accord with the practice.关键词
