| 摘 要： | 针对不同试验条件，对非饱和南宁膨胀土进行了一系列室内对比试验研究，探讨了该膨胀土样的蠕变特性，结果表明：对于一定含水率的非饱和膨胀土样，当上部荷载为50kPa时，其应变随时间呈衰减趋势，且随荷载增加，应变迅速发展，加载6h后，土样应变随时间呈非衰减趋势。

| Abstract: | According to the different test conditions,the paper carries out a series of indoor contrast test study of the unsaturated Nanning expansive soil,discusses the creep of the expansive soil,the results show that the strain of the unsaturated expansive soil with the moisture content attenuates with the time when the upper load is 50 kPa,and the strain rapidly develops with the increase of the load,the strain of the soil is the non-attenuate trend with the time after the six hours load. |
