Fundamentals and experimental testing for soil

Earth-filled embankments, dykes, dams and their foundations are often built with coarse soils. These soils are characterised by a very widely graded particle size distribution and the presence of large particles. To characterise the mechanical behaviour of this type of soils, a triaxial bench was developed to test samples with a diameter of 300 mm and a height of 600 mm. In addition, a...

ABSTRACT
The construction of large dams, currently mainly concrete faced rockfill dams, as well as high road embankments and mining deposits resulting from blasting, requires the knowledge of the mechanical behavior of roills for their design, construction, and maintenance. Significant efforts are made to study them, though most often using smaller specimens, due to the practical difficulties...

Fundamentals and experimental testing for soil

Design of gravel beds for offshore wind turbines gravity foundations is commonly constrained by the lack of laboratory testing methods capable of representing the true mechanical behaviour of coarse granular materials. Standard tests are often unsuitable due to particle size and scale effects, boundary conditions, and installation challenges leading to significant uncertainty in material...

Fundamentals and experimental testing for soil

In Japanese port facilities, rubble mound foundations supporting gravity-type structures such as breakwater caissons are designed using Mohr–Coulomb strength parameters—apparent cohesion (c) and friction angle (φ)—that have been established from large-scale triaxial compression tests on specimens of 300 mm diameter or larger. However, such tests demand specialized equipment and considerable...
