北方风沙区铁路项目施工中风力侵蚀及治理效果监测

沙害是北方风沙区线型生产建设项目遭受的主要危害。通过定位监测与调查监测等方法,对位于该地区的铁路项目的风力侵蚀强度与治沙措施防护效果进行监测,监测数据表明：施工扰动区风力侵蚀剧烈,水土流失严重;采取路基边坡碎石土包坡、路基两侧沙障防护可有效防治项目区风力侵蚀,减少项目区外围风沙流侵害路基,是阻沙固沙、减少沙害的有效措施。

Monitoring to Wind Erosion and Control Effect during the Railway Project Construction in Northern Sandy Area

The wind drift sand disaster is the main endanger to the line type development and construction projects in the north sandy area. Through fixed position monitoring and investigation monitoring,the wind erosion degree, the effect of the sand disaster and the treatment measures have been monitored for a railway situated in the area. The monitoring data indicate that the wind erosion is violent and the soil loss is serious in construction disturbed area. The gravel soil covering roadbed slope, the sand barrier in both sides of roadbed can effectively prevent and control wind erosion in project area and reduce the encroachments to roadbed by the sand flow outside project area, which are the effective measures to obstruct and fix sand and reduce the sand disaster.
