Experimental results of water retention curve of sandstone and its method are presented. Matric suction of sandstone is higher than soils therefore, the water retention curve of sandstone is rarely measured. But retentivity of rock concerns a clastic and a slaking has affect on a slope stability of rock. This higher matric suction is measured by use of psychrometer method and pressure method. Although total suction is measured by the psychrometer method, the matric suction is corrected by use of an osmotic suction. The osmotic suction is calculated from the value of an electric conductivity. Parameters of 'van Genuchten model' for sandstone could be determined by use of proposed method of rock. Matric suctions of rocks are higher than that of soils, so water characteristic curves of rocks are rarely measured.

给出了砂岩持水曲线的实验结果及其方法。砂岩的基质吸力比土壤大，因此很少测量砂岩的持水曲线。但岩石的滞留性与碎屑岩有关，崩解对岩石边坡的稳定性有影响。这种高吸力是用干湿计法和压力法测量的。虽然总吸力是用干湿计法测量的，但基质吸力是用渗透吸力来修正的。渗透吸力是根据电导率的值计算出来的。砂岩“van Genuchten模型”的参数可以用所提出的岩石方法来确定。由于岩石的基质吸力大于土壤的吸力，所以很少测量岩石的水特征曲线。
