摘　　要：使用吹填土进行围海造地是当前拓展沿海地区土地空间的主要方法。该研究在室内土柱模拟试验基础上,分析了曹妃甸围海造陆地区吹填土在固定水头条件下淋洗脱盐过程的技术指标,得出了吹填土的淋洗用水量、脱盐时间等参数,同时探讨了研究区域内土壤在淋洗脱盐时的盐分运移规律、脱盐碱化等问题。该研究可为直接利用吹填土进行生态建设、园林绿化等方面提供参考。Using dredger fill to reclaim land from sea is a primary way for expanding expand land space in coastal areas.Based on soil column simulation experiment,the salt leaching process by dredge fill in Caofeidian area was analyzed under constant water head.The leaching requirement and the desalination time of the dredge fill were obtained.The salt transport and desalination mechanism during salt leaching process were discussed in the study area.The results can provide a reference for ecological construction and afforestation of land which is made from dredger fill.
