铁路路基工程施工期易产生水力侵蚀,对工程所在地的水土流失防治产生较大影响。以现场监测为基础,研究了东北黑土区填方路基的水土流失强度,提出了依据现场监测结果估算路基工程施工期水土流失强度的方法。
During the construction of railway subgrade projects, hydraulic erosion easily occurs, which has a great impact on the prevention and control of soil and water loss in the project site. Based on the field monitoring, the intensity of soil and water loss of the roadbed in the black soil area of northeastern China was studied, and the method of estimating soil erosion strength during the construction period of the subgrade was proposed based on the field monitoring results.
