针对亭子口水利枢纽农田防护工程低地垫高方案的保水性能,在室内大型土柱试验的基础上,建立基于Richards方程的一维饱和-非饱和水流运动数学模型,模拟分析不同防护方案条件下土壤水分的运动过程和保水性能.结果表明:目前拟采用的70 cm耕作层防护方案通过适度压实保水性能良好,所建模型和所得相关成果可以为类似工程提供参考.

To research the water retention performance of lowland heightening farmland protection project in Tingzikou Water Control Pivot, large-scale soil column experiments and one-dimensional saturated-unsaturated flow simulations have been performed. The results show: (1) 70 cm thick arable soil layer with appropriate compaction can ensure satisfying water retention performance;(2) the established model and the results obtained in the paper can provide a reference for similar projects.
