摘　　要：风沙区土壤风力侵蚀模数的客观取值直接影响着铁路工程水土保持措施的设计和效益发挥。以柴达木盆地风沙区格库铁路工程典型取土场为研究对象,采用传统的风蚀监测方法和SL773—2018国标导则指导公式对取土场原始背景、施工期、平整整治后3个阶段的土壤侵蚀模数进行分析研究。研究表明:2种研究方法结果产生差别的主要原因为前者的操作误差和后者的参数取值误差,在原始背景和整治条件下,2种方法均能客观表征土壤侵蚀程度,但在开挖施工期间,应结合集沙仪采集数据作为补充更为合理。The objective value of soil wind erosion modulus in wind-blown sand area directly affects the design and effect of soil and water conservation measures in railway engineering projects.With the typical borrow site of Golmud-Korla Railway Project in the wind-blown sand area of Qaidam Basin as the object of study,the traditional wind erosion monitoring method and the formula in SL773-2018 national standard guidelines are adopted to analyze and study the soil erosion modulus of borrow site in three stages:original background stage,construction stage,and post leveling and remediation stage.The main reason for the difference between the results of using the two study methods is the operation error of the former and the parameter value error of the latter.With the original background and remediation conditions,both methods can objectively represent the soil erosion degree,but during excavation,it is more reasonable to take the data collected by sand collectors as supplement.
