【 摘 要 】

Water of subgrade soils root in atmospheric precipitation, underground water and wet migration. It is clear that the moisture of subgrade have been inclined to reach equilibrium conditions with surrounding environment after many years for highway operation through investigation for variation law of moisture with seasons alternation. The environmental factors of subgrade moisture can be divided into climate condition and groundwater table based on summary for influence factors of moisture equilibria comprehensively. Prediction method of subgrade moisture consist of conventional estimation, regional classification estimation and enhanced integrated climatic model chiefly. Regional classification estimation has been recommend to forecast moisture equilibria due to quantification for impact of environmental factors on subgrade moisture.
