Abstract


Wind erosion the sand burial hazards is one of the sandstorm area railway projects are facing the most serious natural disasters create great difficulties for the conservation of its occurrence will give railway operators and line facilities . Zhang hub is located in the northern part of North China , east-west line total length of 178.96 km , is the main part of the Beijing-Lanzhou railway . This paper relying on research projects , \the indoor experimental analysis , the analysis and discussion of the impact factor of the basic characteristics of Zhang set line embankment , borrow pit and construction roads wind erosion ; through on-site testing and data analysis , and Zhang set line embankment , borrow pit and construction roads wind erosion law study , the following conclusions : (1) the construction of the embankment accelerated role, which might make the embankment local wind speed is greater than the starting wind speed further erosion of surface wind speed , therefore embankment design should be considered in this case , may cause local wind erosion of the roadbed reinforcement; presence of significant exponential relationship between wind speed and sediment load ( 2 ) embankment measurement points ; each measurement point ( 3 ) embankment sediment load is mainly concentrated in the range 20 cm height below the surface , borrow pit the construction detour sediment load is mainly concentrated in the range 30 cm height below the surface ; ( 4 ) points of the embankment erosion intensity embankment height ; (5) quantitative analysis of the embankment , borrow pit and construction roads wind erosion accelerated accelerated erosion factor obtained under different wind conditions .
