Abstract:: In this study, the impact of soil and water loss for construction of three passenger dedicated railways (i.e. Wuhan-Guangzhou passenger dedicated railway, Zhengzhou-Xi’an passenger dedicated railway, and Beijing-Shanghai high speed railway) were quantitatively analyzed and evaluated using the SWII method. The results showed that the impact indices of soil and water loss of these three projects were 0.205, 0.176 and 0.244, which were lower than the average value of impact indices of railways construction projects in China. This also indicated that passenger dedicated railways construction would induce less soil and water loss than traditional railway construction. The causes for the low indices of passenger dedicated railways included less occupation land (3.05 hm²/km) and influence area (0.485 hm²/km), little earthwork volume (5.32×10⁴ m³/km), small amount of soil and water loss (269.27 t/km). In addition, for different passenger dedicated railways, we could shorten the construction period, reduce wasted excavation and increase control area of soil and water loss to mitigate the impact of soil and water loss and protect the eco-environment of the regions along the railways.
