摘　　要：在我国水力侵蚀亚区内选取几条施工中铁路进行现场水力侵蚀实验调查,对铁路施工期水力侵蚀情况调查和研究,并在我国5个水力侵蚀亚区内的铁路施工期水力侵蚀进行人工降雨试验和侵蚀沟调查,研究结果得出5个侵蚀亚区内各铁路工程类型施工期水土流失等级、加速侵蚀因子和侵蚀模数。结论表明,交通工程边坡水力侵蚀程度受施工工程特点影响非常明显,新型构造物的形成将引发严重的土壤侵蚀现象。Several railways,which were constructing,in 5 water erosion regions in China were selected for studying the experiments of artificial rainfall erosion and gully erosion.The erosion grades,accelerated erosion quotients and erosion moduluses of different railway engineerings in construction period of 5 regions were got.The results showed that water erosion degree of tragic engineering slope was obviously affected by the engineering characteristics,new construction would cause serious soil erosion.
