The size of the representative elementary volume (REV) of cracked CCL decreases linearly with the increase in soil LL when LL < 50. The linear fitting result is REV = 90.5 – 1.6 LL, whereas REV change is inconspicuous with a mean value of approximately 10 cm when LL > 50. The sample size of the CCLs for the permeability test must be larger than REV. Before and after three dry-wet cycles, the permeability ratio (K₃/k₀) initially increases and eventually decreases as soil LL increases, and LL at the peak value of K₃/k₀ is 36.1%. However, linear relationships exist between permeability D-value (K₃ − k₀) and soil LL in a semilog coordinate system when LL < 50%, whereas the change in the permeability D-value is inconspicuous with a mean value of approximately 1.67 × 10⁻⁸ cm/s when LL > 50%. The volume and mean width of unclosed cracks are two main factors that determine the increase in permeability after dry-wet cycles. After three dry-wet cycles, these factors decrease as soil LL increases, thereby reducing the permeability D-value.]]> Tue 03 Sep 2019 18:02:06 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35947 j(where K_j is the slope of the SSCC) and the water content gradient in the crack linear expansion stage and the crack linear close stage for different CCL types.]]> Mon 20 Jan 2020 10:31:09 AEDT ]]>
