subgrade erosion

For the characteristics of wind and rain erosion, easy destruction of subgrade slope of northwest of Shanxi highway, planting ning twigs slope test is taken.

针对晋西北公路路基边坡风蚀雨刷易毁的特点，选择了种植柠条护坡试验。

Considered stability, anti-erosion, economic and other factors, this paper, using a comprehensive multi-attribute decision-making law, optimizes the cross section design plan of Soft Rock Filling Materials subgrade in order to select the most economic and stability method.

本文综合考虑稳定性、抗冲刷性、经济性等因素，采用综合赋权多属性决策法对红官公路软岩填料路堤横断面的设计方案进行了优化分析。

However, it is still not clear enough on erosion failure mechanism of the subgrade and there is no uniform prediction model on stability of them currently.

然而目前，山洪冲刷淘蚀作用下铁（公）路基的破坏机理尚不够明确，路基冲刷稳定性的预测模型也没有统一的标准。

Rail subgrade and the ambient area are protected by protective projects to stop wind erosion.

在工程防护方面结合铁路工程本体和铁路两侧一定范围的加固和防护来防治铁路沙害的发生.
