On the Dilatancy of Fine-Grained Soils [PDF]
Geotechnics, 2021 A new evaluation method for the dilatancy of fine-grained soils based on monotonic and cyclic undrained triaxial tests has been established using two elasticity approaches: isotropic and transverse isotropic hypoelasticity. The evaluation of two clays, Kaolin and Lower Rhine Clay, with the new method also shows that the dilatancy of fine-grained soils ...

Effect of Waste Glass on Properties of Treated Problematic Soils
ARO-The Scientific Journal of Koya University, 2023 Soils are the most commonly used construction material in engineering projects. Fine-grained soils especially clayey soil may expand and lose strength when wet and shrink when dry, resulting in a significant volume change. Construction on weak soils has

Soil water characteristics of coarse-grained accumulation soil and their prediction method
Yantu gongcheng xuebao, 2023 The unsaturated state is an important factor affecting the mechanical properties of soil. In view of the lack of researches on soil-water characteristics of coarse-grained accumulation soil, a large unsaturated coarse grained soil triaxial test system is

Zhongguo dizhi zaihai yu fangzhi xuebao, 2022 After the Wenchuan earthquake, many loose solid sources accumulated in the channel, which increased the probability of debris flow. It was difficult to calculate the dynamic reserves of debris flow sediment source accurately. Based on field investigation,
