...Sheng Zhang; Zhao-Qing Li; Chen-Xi Tong; Chen Chen; Guang-Jian Chen; Daichao Sheng The migration of fine particles of gravel–sand mixtures subjected to suffusion plays a significant role in understanding the development of internal erosion-induced failure of hydraulic structures. This paper...

...Jongmuk Won; Incheol Joo Suffusion can be defined as the loss of relatively small soil particles in gap-graded soils without any volume change. In this study, the susceptibility of interaction energy-induced suffusion in sand–clay mixtures is investigated using a laboratory-scale two-dimensional...

...V. S. Ramakrishna Annapareddy; Adnan Sufian; Thierry Bore; Alexander Scheuermann Suffusion experiments were utilised to quantify the evolving degree of heterogeneity in gap-graded soils. Upward flow was imposed on test specimens comprising a mixture layer with varying finer fraction contents...

...Yongjoon Choe; Hangseok Choi; Jongmuk Won Internal erosion by suffusion within a sand–clay mixture may occur as detachment of clay particles, which is induced by a decrease in ionic concentration (IC) along with application of a high hydraulic gradient. Through designed laboratory soil-column...
