中文摘要:通过室内相同条件下清水膜孔灌单向交汇入渗和4种不同泥沙粒度组成的浑水膜孔灌单向交汇入渗试验,研究不同泥沙粒度组成对浑水膜孔灌单向交汇入渗特性的影响;建立浑水膜孔灌单向交汇入渗量、单向交汇时间、湿润锋运移距离与不同泥沙粒度组成的关系;提出不同泥沙粒度组成下浑水膜孔灌单向交汇入渗单位膜孔面积累积入渗量模型、自由面和交汇面湿润锋运移距离模型;并揭示不同泥沙粒度组成下浑水膜孔灌单向交汇入渗相对相同条件下清水膜孔灌单向交汇入渗的减渗特性。结果表明,浑水膜孔灌单向交汇入渗单位膜孔面积的累积入渗量随着物理性粘粒含量d0.01(粒径小于0.01mm的颗粒含量)的增大而逐渐减小;入渗系数K随着d0.01的增大而减小,入渗指数α随着d0.01的增大而增大;在相同入渗时间内,随着物理性粘粒含量d0.01的增大,自由面和交汇面垂直和水平湿润锋运移距离都逐渐减小,减渗率逐渐增大。

Abstract:Through indoor single-line interference infiltration of clean water film hole irrigation and four different clay and sand grades of single-line interference infiltration of muddy water film hole irrigation tests under the same condition, the influence of single-line interference infiltration characteristics of muddy water film hole irrigation under different clay and sand grades was studied, the relationships between single-line interference infiltration of muddy water film hole infiltration volume, single-line interference time, wetting front movement distance and different clay and sand grades were established, the cumulative infiltration volume model and free surface and interference surface wetting front movement distance models for single-line interference infiltration of muddy water film hole per unit area under different clay and sand grades were put forward, and the infiltration reduction feature and influent law of single-line interference infiltration of muddy water film hole irrigation with different clay and sand grades under the relatively same condition of clean water single-line interference infiltration of film hole irrigation were revealed. The results showed that the single-line interference infiltration of muddy water film hole infiltration per unit area of the cumulative infiltration volume was gradually decreased with the increase of physical clay content d0.01 (particle content with diameters less than 0.01mm), the infiltration coefficient K was decreased with the increase of d0.01, and infiltration index α was increased with the increase of d0.01. In the same infiltration time, the vertical and horizontal wetting front movement distances for free surface and interference surface were gradually decreased and the infiltration reduction rate were gradually increased with the increase of physical clay content d0.01.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
