| 中文摘要: |
| 蚁穴系统是由洞穴通道和生化土体构成的复杂间断系统.由蚁酸与粘粒土拌合而成的蛋白泥胶,不仅具有良好的保温、保湿性能,而且对土体的强度和稳定性具有较大的影响.在干燥或潮湿状态下,泥胶对土体的强度和稳定性具有加强的作用;但在饱和状态下,随着其含量的增加,土体的强度和稳定性将降低,并分别呈反"S"型和"先缓后陡"下降型变化;特别是在水流的冲蚀或潜蚀作用下,易使土体结构崩解破坏,并最终导致地面塌陷积水和边坡失稳滑移. |
| 英文摘要: |
| The complicated ant-nest system is made up of nest-way and biochemical soil. The protein soil glue in nest-wall, mixed with ant-acid and clay, not only keeps temperature and humidity, but also influences soil-body's strength and stability greatly. Under the condition of being dry and moist, it can enhance soil-body's strength and stability. But under the condition of being saturant, with the increasing of glue content in soil gradually, its strength and stability go down with the curve patterns of "S" and "slow early and steep late". Structure of saturant soil worked by water erosion is easy to collapse, and finally leads to surface saving water and losing stability. |
