Consolidation
<p>Consolidation of soft sediments stored in the confined disposal facilities or mine tailing dams has challenged the scientists to come up with the best consolidation device for the past 50 years. Since the Terzaghi consolidation theory does not apply in soft sediments due to lack of permeability measurements and self-weight effect, the seepage-induced co...

The mining tailings disposal system is often associated to the construction of large retaining systems, either for the great volume of materials generated by industrial plants or for the impossibility or difficulty of grants for new disposal areas. Due to increasing demand, these impoundments have become much more significant, triggering considerable increase of...

An experimental technique, using a computer controlled triaxial test to evaluate the coefficient of earth pressure at rest, K0, is presented. The method does not require the use of any radial measurement transducers and is free from any side friction effects, typical of oedometer testing. It uses commercial software (GDSlab) which applies ramps of radial stress ...

The paper corresponds to the Pacheco Silva Lecture delivered by the author in September 2014. In the first part of the text, a general perspective of the movements induced by deep excavations in soft soils is outlined. The general report presented by Ralph B. Peck to the 1969 ISSMFE México conference is taken as reference and the progress achieved since t...
