【摘要】 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。更多还原

【Abstract】 The risk estimation model of debris flows in Tianshan Highway was set up with debris flow’s own dangerous degree and damage degree of highway by debris flow.The quantization of risk degree for main debris flow in Tianshan Highway was completed for the first time:for the risk value more than 0.80,it is extremely dangerous;for the risk value between 0.50~0.80,it is very dangerous;for the risk value between 0.25~0.60,it is normally dangerous;for risk value less than 0.25,it is light dangerous.Through the statistical analysis of the risk assessment,the characteristics of Tianshan Highway debris flow and the corresponding prevention and treatment measures was studied.更多还原
