| 摘 要： | 在滨海地区自然环境中，由于滨海盐渍土特殊的工程性质，固化盐渍土作为路基填料的耐久性直接关系到路基的稳定性。通过室内饱水时间模拟试验、干湿循环模拟试验和抗冻性试验，对4种固化盐渍土的水稳性和抗冻性进行了初步研究。试验结果表明，滨海盐渍土经石灰、水泥、SH综合固化处理后，表现出良好的水稳性和抗冻性，可以满足滨海地区公路工程建设的要求。

| Abstract: | In coastal areas, the durability of stabilized saline soils as roadbed fillings directly influences the performance of roadbed because of the negative properties of saline soils. Accordingly, water stability and freeze-thaw resistance of stabilized saline soils are studied. The results of the tests indicate that the coastal saline soils stabilized by lime, cement and SH present good water stability and freeze-thaw resistance, so as to meet the requirements of highway construction in coastal areas. |
