Abstract

Unpaved road and road surface regolith are taken as the research objects in this study, 15 main roads in production and construction projects in Shannxi Province and Inner Mongolia Autonomous Region were investigated, road simulate and artificial rainfall experiments were carried out. The results showed that the road erosion and surface regolith erosion are significantly related to precipitation, slope and regolith thickness, based on the experiments results and literature review, the road and surface regolith erosion prediction equations were established, the imitative results are at significant level (R=0.764,0.937), another set of artificial rainfall experiments were carried out for the test of prediction equations, through the verification of measured data, the prediction values have a significant linear relationship with the measured values (p 0.01), determination coefficient are 0.80 and 0.74 respectively, thus, the prediction equation is suitable for the erosion prediction of roads in production and construction projects, the equation itself is theoretically simple and each parameter can be directly detected in the field, it can be easily operated and used. This study provides new view angle and basis for accurate and comprehensive calculation of soil and water erosion in production and construction projects.
