Research On The Wind And Snow Resistance Of Tunnel Entrance And Highway

The wind and snow flows ( Also called the wind blowning the snow) is a grain of atypical flowing for the snow running with the air ,that is to say it is a kind of weather phenomenon that snow runs with the wind. It has redistributed the natural snow. The area of the wind and snow covers percent 55 the total area of our country, which mainly distributes in Qinghai-Tibet Plateau and mountain area nearby, North SinKiang and Han Mountain , Inner Mongol and the Northeast distrit. The danger to local highway communication caused by wind blowing snow bring greater influence to traffic safety . At the same time, the highway communication infrastructure of our country is still very weak , a lot of highway sections of the area which wind blows snow do not take prevention measurement ,or measurement improper which violates the law of wind blowing snow ,it has not played a role in protecting and aggravated the disaster, and it brings the threaten to the people's life and property.This paper goes on the following work which is based om actual project and analysis the influence on the tunnel mouth caused by wind blowing snow:1.Based on G045 line which is one of 18 east-to-west horizontal line in National highway network plan as a project ,this text analyzes the main factors which may exert an influence on the project in the course of snowdrift,put forward a corresponding prevention measure.2. Use FLUENT to analyze software to carry on the numerical simulation, analyze its result, confirm the optimum scheme by means of comparing different schemes combined with project.3. Propose the project suggestion according to the result of study, offer the reliable basis for similar project.
