摘　　要：通过不同容重土壤对单坑入渗湿润体和含水率分布规律的影响进行试验研究,得出如下结论:不同容重的土壤的湿润体形状具有相似性;容重大的土壤径向含水率在靠近水室的地方比容重小的土壤含水率大;土壤含水率随着垂向距离的增大,先增大后减小。By means of a series of laboratory tests, the paper studies the intluence ot different soil bulK denslues on shapes of wet soil body formed by infiltration from a single pit and the distribution laws of soil moisture Contents in soil body, and draws following conclusions that the shapes of wet soil body with different soil bulk densities pos- sess similarity, the radial moisture contents of large bulk densities in the position near the water room are great than the contents of small bulk densities, and with the increase of vertical distance, the soil moisture contents increase first, then decrease.
