以江苏海门地区典型的滨海盐渍土为研究对象，通过击实试验、无侧限抗压强度试验、室内承载比（ CBR）试验，以及水稳定性试验，研究了水泥和石灰两种改良剂对该类滨海盐渍土性能的影响。结果表明：当水泥添加量12％～14％或石灰添加量10％～14％时，改良土的饱水无侧限抗压强度达到《公路路面基层施工技术规范》规定的二级公路底基层指标；石灰改良土最佳石灰掺入量为12％；水泥对CBR的提升和对盐渍土膨胀的抑制作用比石灰更显著；两种改良剂添加量为6％～14％时，改良土水稳定系数在65％～80％之间；施工中需采取隔断、排水等措施降低水对盐渍土路基的影响。

The coastal saline soil was studied through compaction test, unconfined compressive strength( UCS) test, in-door CBR test and water stability test in Haimen,Jiangsu. The influence of different modifiers on performance of coastal saline soil was analyzed such as cement or lime. The results showed that with the addition of 12%-14% cement or 10%-14% lime stone into the saline soil in mass, the UCS before and after immersion could reach the values required for the subbase of roads grade II.The best lime stone addition was 12%. The cement offered more improvement to CBR and more inhibition to saline soil expansion than the lime. The water stability coefficient ranged from 65% to 80% with the addition of 6% to 14% modifiers. In construction practice, the blocking and the drainage of water and other measures should be taken to reduce the influence of water on saline soil subgrade.
