The column tests on advection-dispersion are commonly used to measure the contaminant transport parameters in soils. The applicability of boundary conditions for analytical modelling of the column tests is under debate. ...

The deformation properties of CFRD (concrete face rockfill dam) are studied through centrifuge tests by building concrete cover plate on the alluvium foundation. Three centrifugal model tests are conducted for the purpos...

The previous studies show that acid rain pH significantly affects the leachability of stabilized heavy metals-contaminated soils. The parameters of diffusion coefficient (De) and retardation factor (Rd) are critical for ...

The end restraint can be eliminated by lubrication sample cap to some extent in the conventional triaxial tests. A comparison is made between the conventional triaxial tests and the end friction reduced triaxial tests in...

Due to their small thickness, high flexibility and tiny sensing element, the tactile pressure sensors can be used to measure the soil stresses and contact forces between soil particles. Hence, the tactile pressure sensor...

The liquefaction resistant rigid-drainage pile is a new type of pile which can be used in geotechnical earthquake engineering. The pile combines the bearing capacity of rigid pile and the drain-ability of gravel pile. Ba...
