1), is based on pore-scale information such as pressure and flow velocities fields. This is the information that can be obtained with the help of pore-scale modelling approaches. Sign in to download full-size image Fig. 1. Homogenization and continuum-scale flow modelling in soils based on ...
The highest modified free swell index value of the samples was obtained in the presence of NaCl solution for all the soil samples. No relationship was found between the total suction, matric suction and the modified free swell index value of the tested soils.Hasan...
in clayey soil, the effective normal stress is lower, and the lower shear strength of pile-soil interface is resulted while the suction decreases between concrete and clayey soil; in shear rate range of 0.4-1.0 mm/min,the increase of pore water pressure is smaller with higher shear rate in...

The solid phase pressure in the work of Coussy (2004) is named as the equivalent pore pressure pE and is defined as the difference between the average pore pressure p* and the interfacial energy U. The interfacial energy is obtained by integration of the capillary pressure with respect to ...
is between about 65 and 85 centibars (cb). This means that although there may be water remaining in unsaturated pores at highersoil watersuctions (e.g., in fine-textured soils), suction lysimeters are incapable of sampling them.Box 7.4shows the common units to describe pressure and vacuum...
