【摘要】 针对山区较为常见的泥石流灾害,分析了公路线路可靠性的影响因素量化标准,提出了泥石流地区线路的安全性与可靠度分析模型。以帕隆藏布流域内的川藏公路为例,确定出线路通过泥石流地区的安全性与可靠度,并进行了分级划分,为线路合理通过泥石流地区提供决策依据,从而达到防灾减灾的目的。更多还原

【Abstract】 In accordance with the relatively common debris flow hazards in mountain areas, the quantized standards of influence factors of the highway route’s reliability are analyzed and the safety and reliability analysis models of the highway route in debris flow regions are put forward. Taking Sichuan-Xizang railway in Polongzangbu basin for example, the safety and reliability of the highway route crossing debris flow areas are determined, and the classification is demarcated, which provides the decision basis for the routes crossing the debris flow regions reasonably, thereby achieves the purpose of controlling and mitigating disasters.更多还原
