摘　　要：依托国道302线阿力得尔至三岔段公路工程实例,对工程沿线路段雪害进行了调查与分析。借助调查数据,对可能发生雪害的路段进行了雪害预测,并评估了雪害危害程度,在此基础上确定需要进行重点防治的重度雪害路段。研究建议采取高分子防雪网、工程弃土建设土质防雪墙进行线外防治,若重点路段受条件限制,不能采取线外防治措施,建议增加相应的雪害提醒标志。Based on the highway engineering case from Alidel to Sancha section of national highway line 302,the snow damage along the route of the project is investigated and analyzed.With the help of survey data,the snow damage prediction is carried out on the road sections that may occur in snow damage,and the hazard degree of snow damage is evaluated,and on this basis,the severe snow damage road sections needing key prevention and control are determined.The research shows that polymer snow defence nets and snow defence walls for the engineering spoil soil construction should be used for off-line prevention and control,and if the key road sections are limited by conditions and off-line prevention and control measures cannot be taken,it is recommended to add the corresponding snow damage reminder signs.
