Indirect verification of suction in cyclic UCS tests of a chemically stabilized soil [PDF]

E3S Web of Conferences
The present study aims to indirectly evaluate the occurrence of suction and its effects in laboratory tests of a chemically stabilized soft soil. To achieve these goals, a series of unconfined compressive strength (UCS) and triaxial tests were performed,

Explicit Modeling of the Cyclic Behavior under a Large Number of Cycles: Application to the Case of Sand

Selected Scientific Papers: Journal of Civil Engineering, 2022
The estimation of deformations after a large number of cycles is a major concern of geotechnical engineers. This paper presents an explicit formulation of the accumulated cyclic volumetric strain.

A simple method for the determination of sensitivity to density changes in sand liquefaction

Open Geomechanics, 2021
Fully saturated loose coarse-grained soils are known to be prone to liquefaction. Conventional laboratory tests for soil liquefaction include usually cyclic testing in triaxial apparatus.

A constitutive model for unsaturated cemented soils under cyclic loading [PDF]

, 2008
On the basis of plastic bounding surface model, the damage theory for structured soils and unsaturated soil mechanics, an elastoplastic model for unsaturated loessic soils under cyclic loading has been elaborated.

Energy Dissipation and Pore Pressure Generation in Stress- and Strain-Controlled Cyclic Triaxial Tests

Geotechnical Testing Journal, 2018
The pore pressures generated in soils subjected to cyclic loadings have been shown to be proportional to the energy dissipated in the soil during that loading.

Effects of cyclic loading on lateral bearing capacity of single pile in silty seabed

Yantu gongcheng xuebao
Under larger wave loading, the bearing capacity of marine single pile foundation will be reduced, even instability occurs. A series of undrained shear triaxial tests on the remolded marine silt in Hangzhou Bay are carried out by means of the GDS triaxial

Dynamic properties and liquefaction behaviour of cohesive soil in northeast India under staged cyclic loading

Journal of Rock Mechanics and Geotechnical Engineering, 2018
Estimation of strain-dependent dynamic soil properties, e.g. the shear modulus and damping ratio, along with the liquefaction potential parameters, is extremely important for the assessment and analysis of almost all geotechnical problems involving ...

Relationship between monotonic and cyclic behavior of saturated soft clay in undrained triaxial compression tests

, 2021
Cyclic loading-induced deformation of soil is a common problem in the engineering practice. In the current practice, however, monotonic triaxial tests are more commonly used in the practice, due to...

Experimental study on the cyclic resistance of a natural loess from Northern France [PDF]

, 2009
In order to analyze the instability phenomenon observed along the Northern High Speed Line of R\'eseau Ferr\'e de France (RFF), soil blocks were taken at a site near the railway, at four different depths (1.2, 2.2, 3.5 and 4.9 m).
