青藏线哈（尔盖）－格（尔木）段位于青藏高原，横穿柴达木沙漠，集沙漠特征与高原气候于一体。不少地段曾因沙害造成行车中断和机车掉道等事故，其中以客城最为突出．在以往相关研究的文献中，确定主风向是以风的频率为主．但在以防止沙子上道为主要目标的铁路防沙中，本文提出的以输沙量为依据所确定的主风向，能为防沙措施提供更为合理的依据．在该段铁路防沙中，采用了竹片栅栏与碎石方格相结合的阻、固措施，其中碎石方格系在铁路防沙中首次使用．经过观测，证实阻沙措施降低了风速；固沙措施增加了地面的粗糙度，大大减少了输沙量，为植物的生长创造了有利条件。在该地采用碎石方格固沙既有使用寿命长，又有取材方便的优点．自防沙工程竣工以来取得了明显的经济效益，同时减轻了工人的劳动强度，确保了该段行车安全． The Qinghai-Tibet line Haergai-Geermu section is located in the Qinghai-Tibet Plateau and crosses the Qaidam Desert, integrating desert features with plateau climate. In many locations, traffic accidents and locomotive off-roads were caused by sand hazards, of which the most prominent is the passenger city. In the literature of previous related research, it is determined that the main wind direction is dominated by the wind frequency. However, in the anti-desertification of railway with the main objective of preventing the passage of sand, the main wind direction based on the sediment transport capacity proposed in this paper can provide a more reasonable basis for sand control measures. In this section of railway sand control, the use of bamboo fence and gravel box combination of resistance, solid measures, of which the gravel box system for the first time in the railway sand control. After observation, it was confirmed that the sand-blocking measures reduced the wind speed. The sand-fixing measures increased the roughness of the ground and greatly reduced the amount of sand being transported, thus creating favorable conditions for the growth of plants. The use of gravel grid sand in this area both the long service life, but also the advantages of drawing convenience. Since the completion of anti-sand project has made obvious economic benefits, while reducing the labor intensity of workers, to ensure the safety of driving this section.
