... in partially saturated sandy soils across varying degrees of saturation and pore-fluid compositions – distilled water mixed with either air or carbon dioxide – using a wave-based approach. This approach comprises multiple input frequencies, minimising subjectivity in signal interpretation. An advanced...

... if the liquefaction resistance of non-saturated soils is higher than that of saturated ones, these soils may liquefy, as well. The increasing interest for cyclically mechanical behaviour of non-saturated sandy soils is due to the fact that desaturation or induced partial saturation can be used as useful mitigation...

...A. Yildiz; F. Graf; S. M. Springman Mechanical contribution of roots to the shear strength of saturated soils is not the only function of vegetation in favour of slope stability. Plants also cause an increase in the strength due to plant-induced suction, resulting from partial saturation. Although...
