| 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. |
