摘　　要：根据内陆盐渍土地基特殊性质,以专题试验研究成果为依据,经优化比选,采用耐久性防腐土工布袋碎石桩、不透水的土工布袋注水泥浆固化桩,以及适用于流软塑状盐渍土的强夯块石墩加垫层三种地基加固处理工法。工程实践表明,技术效果良好,造价低,工程质量易于掌控,简单易行。本成果是针对内陆盐渍土地基而研发的特殊加固工法,具有创新性和开拓性。This paper introduces a research result of new methods improving the inland saline soils. Based on the special charac- teristics of the inland saline soils and the comparison of different soil improvement methods, three methods are found to have both the technical and the cost advantages： geotextile wrapped vibro stone columns, cement slurry in the impervious geotextile tube and the stone piers formed by the dynamic compaction. The geotextile wrapped stone columns cement columns have strong resistant to the corrosive soil environment. Whereas, the dynamic compaction formed stone piers have a good result in treating the super soft saline soils. The construction results indicate that these all three methods can be applied with a fairly simply quality control.
