The monotony and extremum theory of function are applied to prove the geometrical characteristic of error hand for 2D linear segment uncertainty ε(subscript σ) model in theory. The result shows that the error hand has the geometrical shape of "larger ends and smaller middle" or "one end larger and the other smaller". The minimum width and its exact position of the error hand are calculated too. It is proved that the minimum width position of the error hand is near the end with the smaller mean square error.

The results showed that the three straight lines model could fit the soil shrinking and swelling characteristic curves well. The characteristic values of the curves were smaller than 1. This indicated that during the processes of soil swelling and shrinking, the change of the soil specific volume was smaller than that of the soil water content. Values of the geometry factors of four soils studied were equal to 1 at the beginning of shrinking, less than 3 and greater than 1 at other swelling-shrinking phases. The geometry factor values in different phases showed that soil swelling-shrinking was anisotropic and only subsidence occurred at the beginning of shrinking.

结果显示：三直线模型能够很好地拟合4种土壤的收缩、膨胀过程；土壤收缩、膨胀曲线各段的特征值均小于1，这说明土壤胀缩过程中土壤容积的变化速率小于含水量的变化速率；4种土壤胀缩过程中几何因子r大于1而小于3，且收缩初期几何因子r等于1，表明土壤的胀缩是各向异性的，并且在土壤收缩的最初阶段只有垂直收缩。
