| 摘 要： | 以施入保水剂的土壤为研究对象,建立了施入保水剂土壤吸水后的空隙变化模型,并对不同含水率条件下土壤孔隙进行了测定,对模型进行了求参和验证,表明此模型具有较好的模拟效果,并以此为基础对施入保水剂条件下的土体吸水膨胀和孔隙度变化进行了分析,结果表明,保水剂施入量越高,膨胀量增加越大,孔隙度的增加也越大. |
| 关 键 词： | 保水剂 吸水膨胀 孔隙改变模型 |

| Abstract: | The soil with application of water retention agent was taken as an object to establish a model of porosity change, and the parameters of the model were calculated and verified by measuring the porosity of the soil under different moisture conditions. The model was found to have better simulation effects. On this basis, water-swelling property and porosity change of the soil with application of water retention agent were analyzed. The results show that the more water retention agent is applied, the more the soil swells and the more the porosity increases. |
| Keywords: | Water retention agent Water-swelling Porosity change model |
