| 中文摘要 |
| 报道多功能膨胀渗透仪的研制及压实膨润土的渗透测试结果。该装置可用于土壤的团结、渗透、膨胀等实验,具有一物多用的特点,特别适合于难渗透的高压实膨润土(ρ>1.5g/cm3)的研究。在水力梯度为(2—4)×103的条件下,对渗透系数为10-12—10-6cm/s的试样可进行准确测量。该装置的研制,为我国在高压实难渗透性和膨胀性粘土方面的研究提供了条件。 |
| 英文摘要 |
| A multifunctional swell and permeability apparatus has been developed and can be used for many different purposes,for example,the tests of soil for solidifiability,permeability and swellability. It was found that it is particularly useful in the study on a highly compacted and less permeable bentonite of ρ>1.5 g/cm3.With this apparatus,a sample of a permeability in the range of 10-12—10-6cm/s was precisely measured under the condition of a hydraulic gradient in the range of (2—4)×103.It is also useful to study those highly compacted,less permeable and swellable clays. |
