<p>This paper presents the shear strength study of a saturated and unsaturated lateritic tropical soil, via triaxial compression tests on undisturbed (loose) and compacted soil samples. The shear strength of the soil increases hyperbolically with increasing ...

<div style="text-align: left;">After a brief review of a number of developments of unsaturated soil mechanics, the paper presents some applications to engineering problems. The first case involves the collapse of a residual soil in <div style="text-align: ...

This paper presents initial laboratory test results which point to the main source of strength in (unstabilised) rammed earth being due to suction, showing that it can be regarded as an unsaturated soil.

<p>An alternative procedure to determine the hydraulic conductivity function (k-function) based on relationships between saturated hydraulic conductivity and void ratio and between air-entry value and void ratio is proposed. The procedure was applied to determine ...

Scale factors for centrifuge modelling have been traditionally defined using dimensional analysis concepts. This is the case for example of centrifuge modelling of unsaturated water flow. However, scale factors governing suction, discharge velocity and time ...
