In order to study the distribution of water in silt soil subgrade, this paper establish finite element model based on unsaturated seepage theory to research the groundwater level, rainfall, evaporation factors influencing on the moisture content of subgrade and side slope materials. The results show that: the moisture content of suhbgrade exponential growth with the water table. Continuous evaporation...
The paper first analyzes the seasonal variation law of subgrade resilient modulus and water content, and then summarizes the common quantitative adjustment methods, calculation of the equivalence of resilient modulus based upon damage equivalence, for resilient modulus of subgrade in the process of season alterations. Finally, the paper puts forward a seasonal readjustment calculation formula for...
