摘要 膨胀土在温度和湿度的影响下会产生较大变形,造成路基变形开裂。针对弱膨胀土,采用石灰改性的方式进行处治,通过试验参数确定及实体工程铺筑,改性后的弱膨胀土压实合格,可为相似膨胀土工程处治提供技术支持。 The temperature and humidity have an effect on the expansive soil, causing great deformation,which leads to the deformation and cracking of subgrade. In this paper, focusing on treating the weak expansive soil, the lime modification was conducted, and through determination of test parameters and physical engineering paving, the compaction of modified weak expansive soil was qualified, which could provide technique supports for the treatment of similar expansive soil engineering.
