λ can be obtained by the tri-axial compression and seepage test(Zhang et al. 2015b).
This is in contrast to the conventional one-dimensional upward directed seepage tests performed in a modified triaxial chamber.
Ke and Takahashi (2012) studied the mechanical effect of internal erosion on gap-graded non-cohesive soils by conducting one-dimensional seepage tests using a fixed-wall permeameter.
In this study, Toyoura sand was packed in an acrylic cylinder and the unsaturated horizontal seepage test was examined and imaged using an MRI device.
The unsaturated horizontal seepage test equipment for MRI is shown in Fig. 1, and the schematic diagram is shown in Fig. 2 respectively.
Using the self-designed testing system, the seepage tests for cemented broken rocks were conducted, and the impact of different factors on water-resisting ability was analyzed.
This paper focuses on field test results and model analyses of the first set of five niche seepage tests conducted in the Exploratory Studies Facility at Yucca Mountain.
Using an MTS816.03 test system and self-designed seepage apparatus, seepage tests of saturated broken rocks were conducted, and the influence of lithology, axial stress, grain size distribution and loading rate on seepage characteristics was analyzed.
Wang resoundingly simulated gas seepage test in the similar materials using pulverized coal, cement, sand, activated carbon, which has a great boost to the development of similar material (Wang et al. 2017).
The seepage test results compare reasonably well with model results without parameter adjustments, using capillary barrier boundary condition in the niche and two-dimensional and three-dimensional conceptualizations to represent discrete fracture and fracture network for the flow paths.
A mesoscale (21 m in flow distance) infiltration and seepage test was recently conducted in a deep, unsaturated fractured rock system at the crossover point of two underground tunnels.
