首发时间:2024-05-31
摘要:通过对某山区沿江高速公路历史滑坡山区高速公路滑坡风险评估研究灾害数据的分析,提出一套基于滑坡易发性-危险性和高速公路易损性的滑坡综合风险评估框架,构建山区高速公路滑坡风险评估模型。基于沿江高速公路数据集进行了高速公路滑坡易发性-危险性和高速公路易损性两项独立的评价,利用构建的模型对高速公路进行风险评估,结果表明:近期极低风险公路占全线长度的43.56%,低风险公路占35.97%,中风险公路占19.87%,高风险公路占0.60%,无极高风险公路。研究得到的成果可为综合评估滑坡风险提供思路,为减缓或降低山区高速公路滑坡风险提供参考,为风险管理提供科学依据。

research on landslide risk assessment of mountainous highways
abstract:by analyzing the historical landslide disaster data of a mountainous area along the yangtze river expressway, a comprehensive landslide risk assessment framework based on landslide susceptibility hazard and expressway vulnerability is proposed, and a landslide risk assessment model for mountainous expressway is constructed. based on the dataset of riverside expressways, two independent evaluations were conducted on the susceptibility danger and vulnerability of expressways to landslides. the constructed model was used to assess the risk of expressways. the results showed that recently, extremely low-risk roads accounted for 43.56% of the total length, low-risk roads accounted for 35.97%, medium risk roads accounted for 19.87%, and high-risk roads accounted for 0.60%. there were no extremely high-risk roads. the research results can provide ideas for comprehensive evaluation of landslide risresearch on landslide risk assessment of mountainous highwaysk, reference for mitigating or reducing landslide risk on mountainous highways, and scientific basis for risk management.
