摘要
数值模拟是认识渗灌条件下土壤水分运动规律的重要方法之一,其可为渗灌工程的实施提供理论指导。为降低渗灌条件下土壤水分运动数值模拟研究的成本,在渗灌条件下土壤水分运动数值模拟软件的设计方法上进行了探讨,分析了软件实现的功能,提出了一种渗灌条件下土壤水分运动数值模拟软件的开发模型,并采用面向对象的方法和迭代-增量式的开发过程实现了该软件。本软件能够应用于渗灌条件下土壤水分运动数值模拟,能够模拟土壤初始条件、灌水压力、渗灌管特性和计算区域边界条件对土壤水分运动的影响,能模拟渗灌条件下土壤水分的再分布过程。软件运行可靠、操作方便,具有一定的通用性。
Numerical simulation is one of the important methods for apprehending law of soil water movement.It can provide theoretic guidance for enforcement of sub-irrigation.In order to cut down the cost of numerical simulation of soil water movement under sub-irrigation,a method of software development for numerical simulation of soil water movement was approached in this project.The function that the software should bring about was analyzed.A software development model for numerical simulation of soil water movement was brought forward,and numerical simulation software was developed by analyzing,designing,programming,repeated proceeding and progressing based on object-oriented method.This software can apply to numerical simulation of soil water movement under sub-irrigation and the effects of initial condition of soil,water head in porous pipe,properties of porous pipe and boundary condition of calculating domain on soil water dynamics.At the same time,the software has ability of redistribution process simulation of soil water under sub-irrigation.The software can be used widely and reliably in sub-irrigation numerical simulation,and operated expediently.
