摘　　要：高速公路工程建设具有线路长、工艺复杂、建设周期长的特点。在建设过程中,不同地区的立地条件、水土流失特点、地形分布、地貌特点、施工工艺等环境影响因素存在较为明显的差异。从高速公路工程建设的水土流失影响因素出发,分析其特点,并探讨了水土流失防治思路和方法,提出了高速公路的水土流失防治需要根据施工组织时段管理优化施工时段,按照水土流失防治分区,点线结合布设防治措施和采取多样复合防护措施,来提升整体防治效果,规避环境风险。Expressway project construction has the characteristics of long route,complicated construction technologies and long construction duration. In the construction process,different areas vary considerably in their environmental influential factors including site conditions,soil and water loss characteristics,terrain distribution,topographical features and construction technologies. In the light of the influence of expressway construction on soil and water loss,this paper analyzes the soil and water loss characteristics of expressway construction and discusses the idea and methods for its prevention and control. It is proposed that construction management should be optimized according to different construction stages and the combined measures should be taken along the route in the ways of points-lines-areas according to the zoning of soil and water loss prevention and control to improve the overall prevention and control effect and avoid environmental risks.
