摘要
针对毛乌素沙地的特征,设计采用机械固沙和植物固沙相结合的方案,即树枝沙障及经编防风固沙网格先期防风固沙,沙障内种植沙生植物后期固沙。建立由高立式沙障、沙柳方格、土工合成材料沙障以及植物防护带组成的,具有阻沙、固沙等综合功能的完整防护体系。并对此铁路风沙害防治措施进行评价,为在类似地区推广铁路风沙害防治的技术设计方案提供依据。
In view of features of Maowusu Sandy Land, a scheme of combining mechanical sand fixation with sand fixation by plants is planned, which is to use branches sand barriers and warp - knitted nets in early phase and planting sand plants inside sand barrier in later phase for sand fixation. An integrated protective system with comprehensive functions of blocking sand and fixing sand is set up formed by high vertical sand barrier, Salix psammophila checkerboard, sand barrier of geo - synthetics and plant protective belts. And the measures of controlling wind and sand harm to railway is evaluated, which is to provide basis for popularizing the planning scheme of controlling wind and sand harm to railway in the same districts.
