针对铁路建设过程中的典型坡面进行了野外人工模拟降雨实验

以定量研究铁路施工引起的水土流失量。实验结果表明 :(1)弃渣小区入渗率大

在试验雨强下没有产流。但在有上坡来水的情况下

极易发生沟蚀

次降雨侵蚀量可达 45 0 kg/ m2

远远大于其它坡面面蚀的侵蚀量 ;(2 )在实验雨强下

各小区的产沙量依次为 :对大雨强

施工路堑 >施工便道 >施工营地 >荒坡小区 ;而对小雨强

施工路堑 >施工营地≥荒坡小区 >施工便道。路堑小区的产沙量明显大于其它各小区

为铁路施工期水土流失防治的重点坡面 ;(3)各小区的累积产沙量与时间

累积径流量与时间之间均具有幂函数关系

The artificial rainfall experiment has been designed for analysing erosion of typical slopes during the railway construction

to quantify the runoff and soil loss.The results prove that the sediment yield of the dumped soil plot is much larger than any other plot

and aliable to develop rill erosion. The another is the surface erosion yield of the uncovered slope plot is much larger than that of nature slope

the constructing road and rentation.
