Abstract

In order to study the laws of snow drifting distance from the cave entrance and the main influencing factors under the multi-parameter coupling conditions of the entrance/exit section of high altitude highway tunnels in cold areas, and to improve the safety of traffic in the entrance/exit section of tunnels in cold areas, firstly, the climatic characteristics of the north and south slopes of the Tianshan Victory Tunnel were collected, and it was found that there were obvious climatic differences in the climatic characteristics of the north and south ends of the Tianshan Victory Tunnel; Secondly, the data collection of snow drifting distance under multi-parameter coupling conditions in the entrance/exit section of high altitude tunnels in cold areas was measured experimentally, and the correlation analysis of the independent variables wind speed and snowfall on the snow drifting distance of the cave entrance was studied by using the method of statistical analysis, and the prediction model of snow drifting distance of the entrance/exit section of high altitude tunnels in cold areas on windy and snowy days was established. The results show that the prediction model has a good fit, which lays a foundation for the study of safe traffic in the entrance and exit sections of high-altitude tunnels in cold areas.
