铁路工程水土流失防治技术体系探讨

Discussion on Water and Soil Conservation Techniques for Railway Projects

铁路工程穿越空间大、地貌类型复杂多样,不同地貌类型的水土流失差异较大,因此有针对性地防治铁路工程所经不同地形地貌区的水土流失,有利于保护铁路工程沿线的生态环境。依据在建合福铁路安徽段工程施工实际,采用资料收集法与对比法,构建了水土流失防治技术与措施体系,对比了平原缓丘区与低山丘陵区目前已实施的水土保持投资额,得出低山丘陵区应为合福铁路安徽段工程水土流失治理重点区域的结论,为类似工程水土保持工作的开展提供参考。

Railway projects pass through numerous spaces and complicate terrains, different terrains witness different degrees of water and soil erosion, so pertinent techniques should be adopted to prevent water and soil loss in regions of diverse topographic conditions, and to protect ec- ological environment along the railway lines. According to the construction status of Anhui Section of Hefei-Fuzhou Railway, data collection and comparison method was used to establish water and soil loss prevention techniques and measures, and compare the investment in water and soil preservation on plains with gentle slopes and in low hilly areas. It was concluded that low hilly areas are major regions for water and soil erosion control along the Hefei-Fuzhou Railway, and the research provides references for the water and soil conservation in similar projects.
