The research objects of this study are the railway slopes which were treated with pressure spraying in the construction of Suiming-Chongqing railway.The variations of soil water of the road-slopes were monitored in different slope positions

various slope aspects during four seas-ons.The results show that soil water content peaked at the upper slope position in October

as high as 18.3%.For the other three seasons

the water contents were significant higher at the foot slope than at the upper and middle slopes.No significant difference of soil water were found among four slope aspects in January and October

while in April and July

soil water contents on shady slopes were significant higher than those on the sunny slopes.Soil water contents peaked in October on all the three slope positions.On all four slope aspects

soil water contents in January and October were significantly higher than those in April and July.Significant relationships were identified between soil moisture contents of different slope positions

slope aspects and seasons

except that soil moisture on foot slopes were affected by season changes only.All relationships were positive except between seasonal variations and slope aspects.Seasonal variations of soil moisture were related closely with slope positions rather than with slope aspects.
