This paper focuses on the influence of joints on seepage capacity of a soil mass, the water infiltration range, the area of the wet zone, and water content distributions. Tests were performed using a self-designed seepage device to determine the hydraulic conductivity of loess samples with natural joints. The test results indicate that joints greatly improve the seepage capacity of a soil mass; the depth and quantity of infiltration for the jointed sample are larger than those for the intact sample. The infiltration depths of the jointed sample are about 2.6 times that of intact specimens, and the measured areas of wet zones of the jointed sample are about 2.2 times that of an intact sample. Due to the existence of the joint, higher water content is observed at the joint location. In comparison, the water content distributions are relatively horizontal for the intact sample.

本文着眼于节理对土壤团块的渗透能力，水的渗透范围，湿区的面积和水含量分布的影响。使用自行设计的防渗装置进行测试，以确定具有天然节理的黄土样品的水力传导率。试验结果表明，节理大大提高了土壤的渗流能力。接缝样品的浸润深度和数量要大于完整样品的浸润深度和数量。接缝样品的浸润深度约为完整样品的2.6倍，接缝样品湿区的测量面积约为完整样品的2.2倍。由于关节的存在，在关节位置观察到较高的水含量。相比下，
