| This paper carries on an in-depth study on traffic safety at tunnel, Including the factors of road accident at tunnel import and export, the driver heart rate, the test analysis of the eye movement state, and getting the conclusion of the characteristics of incidents on this basis. We also put forward the suggestion. And authenticate the securitythe of the proposed construction of the anti-snow shed in special weather conditions,With the booming national economy, China's transport sector is growing rapidly.Construction of the expressway which is more rapid development at an unprecedented rate.The construction of the tunnel can not only shorten the distance, lower slope, improve alignment, reduction of ice, snow disasters have played an important role, but also to protect the natural environment and achieve sustainable development have also played an important role in.But with the extensive tunnel construction in highway, the traffic safety at tunnel also attracted wide attention. In particular, as highway construction technology increasing, a large number of specialty built large tunnels. So as a special access road-how to protect the safety of transportation tunnels is particularly important.As the high point of the tunnel accident import and export sections become the focus of this article.In this paper, the Western Han Dynasty Qinling Tunnel Highway Safety Research Group based access to a large number of relevant literature, the use of advanced electrical theory from the Health and environmental impact of the driver by special start, concerned about the driving environment of the driver, and find out high tunnel accident causes and propose measures to improve it.The idea of such research in the field of road safety research has some innovative.At the same time that this connection through the tunnel entrances to the bridge set against the snow shed, especially in dense areas in the tunnel group.And anti-snow shed for special weather conditions in the safety of using ANSYS simulation technology for the security authentication.The study of anti-snow shed in this paper is the initiative study. |
