| 摘 要： | 为了研究泡沫轻质土的性能与配合比之间的关系，通过室内试验，系统地分析了在不同的配合比设计下泡沫轻质土的流值、湿重度、无侧限抗压强度的变化规律。结果表明:在其他条件保持一致的情况下，随着水固比的减小，泡沫轻质土的流值会逐渐减小，而泡沫轻质土的湿重度和无侧限抗压强度会逐渐增大；同时，掺入适量的粉煤灰有利于提高泡沫轻质土的性能。

Experimental Study on Performance of Foamed Light-weight Soil |
| |
| Abstract: | In order to study the relationship between the properties of foamed lightweight soil and its mix proportion, through the indoor experiment, systematically analyzes the change rule about flow value, wet density, unconfined compressive strength of foamed lightweight soil under the different mix proportion design. Experiments have shown that, in case other conditions remain consistent, flow value of foamed lightweight soil will gradually decrease, its wet density and unconfined compressive strength will gradually increase with the decrease of water-solid ratio; at the same time, it is more beneficial to increase the properties of foamed lightweight soil mixed with appropriate fly ash. |
