工程堆积体坡面 植物篱 的减流减沙效益 及其机理研究

, 2015
生产建设项目在施工及生产过程中会产生大量工程堆积体，而堆积体的土壤侵蚀 模数远高于自然坡面，极易产生严重的水土流失，为探索工程堆积体水土保持的有效 措施，本研究利用宽 5m，长 20m 的标准径流小区，通过野外模拟径流试验，在 24°、 28°、32°三种坡度下，采用 35L/min、45 L/min、55L/min 三种放水流量，研究了工程 堆积体坡面应用植物篱措施后的侵蚀过程、减流减沙效益及其侵蚀动力机理，并分析 了其控蚀能力的时序变化。得到了以下结论： （1 ...

工程堆积体坡面侵蚀过程及水动力指标对入流形式的响应

Shuitu Baochi Xuebao
目的为揭示不同入流形式对坡面侵蚀产沙及其水动力学特性的影响。方法基于人工模拟入流冲刷试验，试验设计2种入流形式（股流、面流）和3种入流量（4、8、12 L/min），研究坡面侵蚀过程对入流形式响应机制。结果1）股流和面流下，坡面产流产沙过程基本一致，产流过程均呈现从跃变到稳定，产沙过程呈现先快速降低再波动减小趋势；相比面流，土壤侵蚀率在股流下表现出更强的波动性，其变异系数高达71.49%~111.94%。2）坡面平均流速在股流下显著高于面流（p<0.05），其幅度高达28.15%~52.85%。3）
