In order to obtain engineering design parameters of improved soil, to have after lime Lidu clay to join admixture load condition simulation experimental study of dry-wet circulation process, its swell-shrink deformation change rule.Under loading condition, different ratio of sample with wet and dry cycle times increase in the relative and absolute swell-shrink ratio decreases.Lime amount within a certain range, the absolute and relative of the soil swell-shrink ratio decreases with lime content in soil is increased.%为获取改良土工程设计参数,对李渡红土加入掺合料石灰后,进行了有荷载条件模拟干湿循环过程的试验研究,得到了其胀缩变形变化规律,指出有荷条件下,不同配比的试样随干湿循环次数增多其相对和绝对胀缩率都在逐渐减小;石灰量在一定范围内,土样的绝对和相对胀缩率随土料中含石灰量增多而减小.
