针对五道梁至雁石坪风沙特点及沙害的严重程度,采取阻、固相结合的措施,在铁路路基两侧设置石方格沙障、喷洒固沙剂和挡沙栅栏,有效地防治了沙害,为高原旱寒地区铁路治沙积累了宝贵经验。 Aiming at the characteristics of sandstorm and the severity of sand damage from Wudaoliang to Yanshiping, a combination of blockage and solidification was adopted to set up sandstone barriers, spraying sand-fixing agent and sand-blocking fence on both sides of the railway embankment to effectively control sand damage , Which has accumulated precious experience for railway sand control in dry and cold areas of plateau.
