从滨海地区盐渍土的工程应用角度出发,利用水泥对其进行改良试验研究,在明确水泥改良盐渍土强度形成机理的基础上,分析了滨海地区盐渍土的抗剪强度、抗压强度、水敏感性、融陷、膨胀特性随改良剂用量、龄期的变化规律。试验结果表明：滨海地区盐渍土经水泥改良处理后,其抗剪、抗压强度和水敏感性明显改善,融陷及膨胀现象得到有效控制,可以用作高等级公路路基填料。
從濱海地區鹽漬土的工程應用角度齣髮,利用水泥對其進行改良試驗研究,在明確水泥改良鹽漬土彊度形成機理的基礎上,分析瞭濱海地區鹽漬土的抗剪彊度、抗壓彊度、水敏感性、融陷、膨脹特性隨改良劑用量、齡期的變化規律。試驗結果錶明：濱海地區鹽漬土經水泥改良處理後,其抗剪、抗壓彊度和水敏感性明顯改善,融陷及膨脹現象得到有效控製,可以用作高等級公路路基填料。

From the point of view of engineering application of salinized soil at coastal area, experimental study is performed for improvement with cement. On the basis of understanding the mechanism of improving strength of salinized soil with cement, the changing rules of shearing strength, compression strength, water sensitivity, thaw collapsibility and expansibility of salinized soil at coastal area along with dosage and age of modifier are analyzed. The result shows that: the shearing strength, compression strength and water sensitivity of improved salinized soil with cement has improved obviously. Thaw collapse and expansion is controlled effectively. The soil could be used for filling of subgrade of high class highway.
