%X To verify the applicability of <i>Guidelines for measurement and estimation of soil erosion in production and construction projects </i>for expressway projects, the soil and water loss at an expressway project under construction in Southwest China was predicted based on the Guideline. The result was compared with that of the analogy method. Result shows that soil and water loss in subgrade engineering area, auxiliary facilities area and waste disposal sites are the most severe, and most of the soil erosion occurs in construction period. The difference of calculation results between the Guidelines and the analogy method is mainly reflected in the area of bare slope due to excavation of project, while other soil erosion types shows little difference. The application of the Guidelines in the prediction of soil erosion in linear projects is complicated but more practical for point projects.
