摘　　要：针对鲁北地区盐渍土特性,结合济乐高速公路项目,采用石灰、粉煤灰、水泥及高炉矿渣等无机结合料作为改良剂,对鲁北地区典型盐渍土进行了单掺和双掺不同配比下的耐久性试验。试验研究结果显示,单掺石灰无法满足长期路用性能,加入水泥等改良剂后加固土具有较好的力学性能和耐久性,可以满足长期路用性能要求。In light of typical characteristics of saline soil in northern Shandong region,combined with the construction of highway projects from Jinan to Naolin,durability test was conducted by using inorganic binder such as lime,fly ash,blast furnace slag and cement under different proportions of blending to modify typical saline soil in northern Shandong region.The test results show that the single-doped lime was unable to meet the long-term pavement performance.Joining cement could improve the mechanical properties and durability significantly.
