摘　　要：为了探索滨海滩涂盐碱地区暗管洗盐工程设计参数,运用溶质运移理论分析了脱盐标准与冲洗时间及冲洗定额之间的关系,研究了暗管工程设计参数(埋深、间距、管径)的影响因素及其理论模型,提出了牛顿迭代法计算方法。通过实例分析验证,得出暗管参数设计理论及方法是合理的,排水区的盐渍化土壤处于脱盐状态,满足作物生长发育的要求,为我国盐碱地改良工程规划提供了技术参考。The aim of this research is exploring the design parameters of underground pipe engineering for soil desalination in the coastal saline areas.Based on the solute transporting model,the relationship between the standards of desalination and leaching time,and leaching quota were analyzed.The calculation methods of the underground pipe engineering design parameters（depth,spacing,tube diameter） were also suggested.Case analysis shows that the underground pipe design parameters theory and method are reasonable;the drainage areas is in desalination state and meet the requirements for crop growth,which provide the important technical support for the planning of land improvement.
