不同防护措施下临时堆土区土壤侵蚀情况监测研究
|
摘要
模拟生产建设过程中的临时堆土,对临时堆土区在不同防护措施下的土壤侵蚀情况进行了监测,分析研究了不同堆放方式和不同防护措施下临时堆土区的土壤侵蚀情况。结果表明:临时堆土摊平堆放的土壤侵蚀系数较自然堆放平均减少3.39%~31.76%;临时堆土洒水处理后,土壤侵蚀系数要明显低于拍实处理和无处理;建议对开挖土方顶部进行适当平整,同时对开挖土方进行人工洒水,使其表面均匀湿润后堆放,可有效降低风蚀量。
The paper simulated temporary soil pile during the process of production and construction,monitored the soil erosion of the temporary soil pile area with different protective measures and analyzed the soil erosion of the temporary soil pile area in different stacking modes and with different protective measures. The outcomes show that a) the soil erosion coefficient of temporary soil pile in spreading method averagely decreases 3.39%-31. 76% comparing with that of natural stacking; b) after watering,the soil erosion coefficient of temporary soil pile is obviously lower than that of patting treatment and without treatment and; c) it suggests to properly level the top of excavated earthwork,in the meanwhile,to spray water on the excavated earthwork for uniform wetting which can effectively reduce the amount of wind erosion.
