Abstract:Research purposes: Our country has many railways across the desert areas,in order to guarantee the safety of railway operation,all kinds of control project is essential. When we design the railway protection project against sand and wind,the main direction of wind is especially important. In reality,the meteorological data in a lot of the desert of railway traversing areas is not comprehensive,so we can't know the local main direction of the wind. This paper get a method to judge the main wind direction through the analysis of dunes form and direction along the railway for sand and wind prevention project design.
Research conclusions: This paper get a method to judge the main wind direction through the analysis of dunes form and direction along the railway. On the basis of determining of dunes from and direction we get a conclusion that the main wind blow from slope against wind to another. Take the Taklimakan desert as an example to prove that the method is very useful for building the new railway and protection project against sand and wind. In addition,the wind speed also influent the form of sand dunes,the detailed relationship need the further research.
