A semi-empirical relationship for the small-strain shear modulus of soft clays [PDF]

E3S Web of Conferences, 2019
The small-strain shear modulus (Gmax) is a soil property that has many practical applications. The authors compiled a database of Gmax measurements for 40 normally consolidated to slightly overconsolidated low to high plasticity clays.

Influence of time on the small strain shear modulus of an allophanic volcanic ash [PDF]

E3S Web of Conferences
The small strain shear modulus is an important parameter in the assessment of soil dynamics problems. Studies on the small strain shear stiffness of volcanic ash remain rare probably because globally they cover just under 1% of the land surface. However,

Characterization of Small-Strain Shear Modulus Through DAS

9th International SUT Offshore Site Investigation Geotechnics Conference Proceedings “Innovative Geotechnologies for Energy Transition”, 2023
The offshore subsurface is a highly dynamic place where seismic waves are constantly generated due to the presence of offshore infrastructure, earthquakes, landslides etc. In recent years, Distributed acoustic sensing or DAS has drawn the attention of geologists and geophysicists for its capability of monitoring seismic activity.

Experimental study on dynamic shear characteristics of loess under cyclic torsional shearing

Yantu gongcheng xuebao, 2020
The unsaturated intact loess has remarkable structured properties. Its structure is damaged by wetting and cyclic shear action, which leads to the development of shear and subsidence deformation of loess under earthquake.

Very-small to large strain dynamic behaviour of unsaturated sand in a wide range of suction [PDF]

E3S Web of Conferences, 2020
Shear modulus (Gmax at very small strain and G at large strain) and constraint modulus at very small strain (M) are important soil parameters for static and dynamic analysis in geotechnical applications.

Small-Strain Shear Modulus and Strength Increase of Cement-Treated Clay [PDF]

Geotechnical Testing Journal, 2010
Abstract A simple nondestructive technique was used as an alternative method to monitor the hardening of cement-treated clay as a function of time. The principle of this monitoring technique is based on the use of bender elements to measure the small-strain shear modulus (G0) at various time intervals. The strength increase was monitored

Enhancing the CPT correlation with the small strain shear stiffness of sands

Ain Shams Engineering Journal, 2017
The cone penetration test (CPT) is a valuable geotechnical insitu test. Yet, the CPT correlations with the small strain shear modulus and seismic shear wave velocity still need more research to enhance their accuracy.

Mechanical Properties and Engineering Applications of Special Soils—Dynamic Shear Modulus and Damping of MICP-Treated Calcareous Sand at Low Strains

Applied Sciences, 2022
Calcareous sand deposits are widespread along the shoreline in tropical and subtropical regions. Microbially induced calcite precipitation (MICP) treatment is a new method for improving the soil’s stiffness and strength.

Influence of strain rate and acceleration on the behaviour of reconstituted clays at small strains [PDF]

, 2010
This paper attempts to bridge the gap between the wellknown characteristics of strain rate-independent elastic stiffness and of the time-dependent behaviour of clays at large strains.

Small-strain triaxial tests and constitutive modeling of Shanghai soft clays

Yantu gongcheng xuebao, 2018
In order to reduces the influence of the existing buildings in the surrounding area, the surrounding soil of the new project usually requires the control of the small strain state (0.001%~0.1%).
