Article
The influence of different proportions of clay minerals on the moisture density relationship and index properties of clay soils are not clearly understood because of the different factors that come into play in natural soil formation. This study used 11 different remolded samples prepared by combining double mixtures of commercially available powde...

Constructing road pavement and highways in tropical countries usually requires using lateritic soils as pavement material. The degree of compaction during the placement of these lateritic soil materials needs to be verified for compaction quality control. The conventional geotechnical methods usually used in compaction verification are invasive, la...

The behaviors of high-plasticity clays depend largely on the clay mineral content. Recently, it has been observed that sudden slope failures of most clay slopes occur in regions pronounced with repeated rainfall and sunny climate. The reason for this is still unclear. Examining the effect of clay minerals and drastic weather changes on shear streng...
Article
True triaxial tests on clay mixed with gravel were carried out under complex stress state to simulate the loading process of core wall elements under water storage process, and loading was applied from the minor principal stress direction. Under initial state, the major principal stress and the second principal stress were adjusted with constant mi...
Article
Series of testing on coarse grained soils were carried out with a true triaxial testing apparatus. The loads were applied from the major principal and minor principal directions, respectively, to simulate the construction and water impounding process of a rock fill dam. The stress and strain relationships induced by the different loading methods we...
Article
Through numerical simulation based on the particle flow method, DEM numerical test samples are generated in accordance with the results of laboratory tests on standard sand. Using gravity deposition modelling of irregular sand particles, samples of biaxial test assembled by long particle units are generated. Different steps of deposition are applie...
