Large-Scale Triaxial Tests on Dilatancy Characteristics of Lean Cemented Sand and Gravel [PDF]
Frontiers in Earth Science, 2021 The dilatancy equation, which describes the plastic strain increment ratio and its dependence on the stress state, is an important component of the elastoplastic constitutive model of geotechnical materials. In order to reveal their differences of the dilatancy value determined by the total volume strain increment ratio and the real value of lean ...

Large-scale triaxial and box testing on railroad ballast: a review [PDF]
SN Applied Sciences, 2019 AbstractThe use of railway transportation systems has been increased throughout the years. The conventional ballasted tracks have been used widely in many countries around the world. Ballast material is the basic element of ballasted tracks. Ballast degrades and deforms after service.

Large-Scale Triaxial Testing of TDA Mixed with Fine and Coarse Aggregates
Buildings, 2023 The number of scrap tires discarded worldwide is increasing annually. Stockpiling these tires is not a viable option due to environmental concerns and space limitations. Landfilling is likewise unacceptable and is not permitted in many areas. Recycling these tires is the best alternative.

Study of Sericite Quartz Schist Coarse-Grained Soil by Large-Scale Triaxial Shear Tests
Frontiers in Physics, 2020 The large-scale triaxial consolidated-drained (CD) and consolidated-undrained (CU) shear tests were carried out to investigate performances of the sericite quartz schist coarse-grained soil on stress-strain, deformation, and strength under four different

Large-scale triaxial tests of dense gravel material at low confining pressures
Soils and Foundations, 2014 AbstractThe results of a series of large-scale triaxial tests performed on dense, prismatic gravel specimens, with a height of 50cm and a cross-section of 23cm×23cm, are described. The specimens were prepared at a density equal to approximately 95% of the maximum density at the optimum moisture content. Deformations were measured locally using vertical

Deformation characteristics of coarse granular materials in large-scale true triaxial tests
Yantu gongcheng xuebao, 2019 The deformation behaviors of coarse granular materials under three-dimensional stress state are crucial to the settlement of earth-rockfill dams. A series of tests under constant minor principle stress and constant coefficient of intermediate principle ...

Large-scale triaxial wetting deformation tests and laws of gravelly soil core materials
Yantu gongcheng xuebao, 2020 Wetting deformation of water storage has always been a technical issue that restricts the long-term safety operation of high earth-rockfill dams. The wetting deformation tests have been commonly carried out for rockfill materials, but seldom for gravelly

Large-scale triaxial test study on wetting deformation characteristics of rockfill materials
Shuili Shuiyun Gongcheng Xuebao, 2023 The wetting of rockfill material can easily lead to the uncoordinated deformation between it and the core wall, thus causing longitudinal cracks at the top of the dam and endangering the safety of the dam.
