摘　　要：应用张力计、热传导探头等吸力量测手段,对山西省运城地区黄土的吸力特性进行试验研究,测出了该黄土在脱湿过程的土-水特征曲线,该法较压力板法简单,还用FredlundandXing(1994)方程对实测数据进行了拟合。An experimental study on suction characteristics of the loess in Yuncheng Region is conducted by using the method of tensiometer, thermal conductivity sensor, etc. The soil-water characteristic curve of this kind of loess in drying procedure is obtained. This method is simpler than the method of pressure plate; and the Fredlund and Xing Equation (1994) has been used to confirm the measured data.
