| 摘要： | This study presents recent research on the effects of the soil suction and the environmental conditions on the soil drying rate. A series of soil suction tests using thermocouple psychrometer method and the drying rate tests using the environmental chamber were conducted in this study. A review of soil suction theory was also conducted. The results of the experimental program show that both suction and relative humidity have direct effect on the soil drying rate. Drying rate decreases with an increase in soil suction for each soil. As compared to the suction, relative humidity has more significant influence on the soil drying rate. |
