The Research On The Melting Snow Of Tunnel Opening Based On The Wind And Solar Power

Nearly 40% of the goods in our country have been transferred through the expressway,and the expressway has become an important booster for the development of the society.The tunnel is at the critical point of road traffic,and the tunnel entrance is the key to the transition from the open section of the highway to the full closed tunnel,which is called the throat of the road traffic.Traveling from ice free road to the icy road,drivers tend to tunnel traffic difficulties underestimated cause traffic accident and traffic congestion,so the tunnel has become one of the key parts of snow to ice cold regions and freezing rain area at home and abroad,It is of great significance to control the traffic accident rate of the tunnel entrance to reduce the accident rate and keep the traffic flowing.At the same time,we use the abundant wind energy resources and solar energy resources in Inner Mongolia area to provide electricity for snow melting and ice melting system through wind and solar hybrid power generation system.This topic research tunnel entrance melting ice based on wind and solar energy complementary power generation,the carbon fiber hotline is laid on the bottom of the asphalt concrete pavement,and it is transported heat to the road surface for snow melting and ice melting.Asphalt concrete to transfer power carrier,the thermal conductivity of asphalt concrete is very necessary to study the change of the temperature field,the thermal resistance of asphalt concrete is 0.0081(m~2,K)/W,thermal conductivity is 6.1019W/(m,K).Layout of carbon fiber hotline in asphalt concrete has a great influence on the ice snow melting,by studying the heating radius of the carbon fiber hotline,found that the layout and heat flux of the carbon fiber hotline has the following relationship:F(x)=2ln(-36.1427+0.2926x).Analyzed the various environmental factors influence on snowmelt deicing at various stages,and the heating uniformity coefficient quantify the heating uniformity,found that heating uniformity was mainly affected by wiring spacing,the wiring spacing greater heating uniformity is worse;the effects of different forms of wiring on the melting ice of contrast,that affect the wiring form negligible;influence of environmental temperature on the melting ice of heating stage is larger,the lower the temperature is,the longer the time of heating time;melt the ice melting stage of the heat flux density mainly affects the heat flux,the greater the melting stage time is short.It provides the design basis for the wind and wind complementary power generation system.The maximum power consumption is how to calculate the ice snow melting system is given at the same time,combined with the engineering the climate to determine the wind power and photovoltaic power generation ratio,according to the number of stand-alone wind turbine power generation and photovoltaic power generation unit to calculate the fan and photovoltaic cell.
