结合泥石流危险度和公路受泥石流损毁度两个指标,构建了天山公路泥石流风险评价模型,实现了对天山公路全线主要泥石流沟的风险值量化:风险值大于0.80的为极度危险,应以防为主,治为辅;风险值在0.50～0.80之间的为高度危险,应防、治并重;风险值在0.25～0.60之间的为中度危险,应以治为主,防为辅;风险值小于0.25的为轻度危险,应以防为主,治为辅。 Combined with the risk of debris flow and highway damage by debris flow two indicators, the Tianshan Highway debris flow risk assessment model is constructed to achieve the Tianshan Highway debris flow across the main channel of the risk value: risk value greater than 0.80 is extremely dangerous, should be prevented Main and cure supplemented; the risk value between 0.50 ~ 0.80 is a high degree of danger, should be prevention, treatment and risk; risk value between 0.25 ~ 0.60 for moderate risk, should rule-based, anti-supplemented; risk Value is less than 0.25 for the mild hazard, should be based on prevention, treatment supplemented.
