摘　　要：为探明非饱和土天然土坡和填方土坡中吸力的变化规律，同时比较不同量测方法的效果，在湖北省枣阳市大岗坡泵站，分别用张力计、热传导探头和滤纸法进行了为期３个月的现场吸力量测。文章提交了吸力测量的结果和有关气象资料。For the study of the suction in natural and fill slopes and comparison of the effects of different measurement methods. the in situ suction of the Dagangpo Pump Station has been measured with tensiometers, thermal conductivity sensors and filter papers for three months. The results of measurements and related meteorological information are presented.
