石灰改良膨胀土无侧限抗压强度试验
Experiment on Unconfined Compressive Strength of Lime Improving Expansive Clay
摘要
Abstract
Based on the expansive clay embankment on Nanyou Highway of Guangxi, the experimental research on the unconfined compressive strength is undertaken. In the test expansive clay samples are all disintegrated when dipping in water, showing poor stability of expansive clay. Some lime improving samples after 7 and 14 days curling are disintegrated when dipping in water, indicating that the unconfined compressive strength sample of lime improving expansive clay should curl 28 days. Lime ratio and curing time both influence the unconfined compressive strength of improving expansive clay. There is optimum adding lime ratio for lime improving expansive clay. During the early days of curling, the unconfined compressive strength increases with curling time.关键词
