中文摘要:针对蓄水坑灌坑内水头高且非恒定和土壤入渗边界复杂的特点,建立了蓄水多坑三维入渗及土壤水分运动数学模型,采用ADI交替方向隐式差分格式结合Gauess-Seidel迭代法对模型进行求解,并进行了试验验证,结果表明计算值与实测值吻合较好,说明所建立的数学模型正确,采用的数值求解方法是可行的。

Abstract: Aimed at the specialties of infiltration head higher and varying under the condition of water storage pits irrigation, numerical model of 3-D infiltration and the soil moisture movement of complicated boundary conditions in water storage pits was established. ADI method and Gauess-Seidel iterative method were used in numerical simulation followed by verification tests. The results showed that the calculated values were in accordance with the experimental results. This indicated the numerical model was correct and the method of solution was feasible.

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.
