摘　　要：在分析了目前铁路工程中土壤风蚀预测常用方法(直接类比预测法)所存在问题的基础上,提出了一种新的适用于铁路工程(或其它交通工程建设)中土壤风蚀预测的计算方法——影响因子对比预测法。通过算例验证表明,其具有较好的适用性和预测精度。Analyzed the disadvantage of the prediction method by straight way analogy which is widely used to predict the mass of wind erosion in railway engineering, a new prediction method by contrast of influence factors is put forward, which is in point for wind erosion in railway engineering, and it is proved to have better applicability and prediction precision by calculating example.
