Elastoplastic Deformation Characteristics of Gravelly Soils

Journal of Geotechnical and Geoenvironmental Engineering, 2013
AbstractThis study explores the elastoplastic deformational behavior of gravelly soils. A series of drained triaxial tests with controlled stress paths [conventional triaxial compression (CTC) and conventional triaxial extension (CTE)] were conducted using large specimens composed of gravelly soils.

Estimating the Shear Modulus of Gravelly Soils

Journal of Geotechnical and Geoenvironmental Engineering, 2005
A special large-scale torsional resonant column apparatus was used to test gravelly soils. Values of small strain elastic shear modulus ( Gmax ) and modulus reduction relationships [shear modulus (G) versus shear strain (γ) ] were measured for specimens of uniform and graded crushed limestone gravel, graded river gravel, standard Ottawa and crushed ...

Experimental Study on Suffusion of Gravelly Soil

Soil Mechanics and Foundation Engineering, 2015
Although internal erosion causes serious hazards to embankments and dams, studies on the emission of fine soil particles and the development of non-uniform penetration of the soil foundation after suffusion do not go far enough. Given that suffusion development is random and complex, this study employed self-designed equipment to conduct tests under ...

Cyclic Loading Liquefaction of Gravelly Soils

Journal of the Geotechnical Engineering Division, 1975
The results of cyclic loading tests on gravelly soils using a 12-in. diam triaxial test apparatus are described. The cyclic stresses required to cause —2.5% and —10% strain of saturated samples of gravelly soils are shown to be somewhat higher than those causing similar strains in sands.

The evolution of holocene reg (gravelly) soils in deserts

CATENA, 1986
Abstract Reg soil is an aridisol developed upon a stable alluvial surface composed of sand to coarse gravel. The objectives of the present study were: (1) to examine the initial evolution of Reg soil properties with time; (2) to assess and explain the rates of development of different properties; (3) to establish the suitability of different soil ...

A New Vs-Based Liquefaction-Triggering Procedure for Gravelly Soils

Journal of Geotechnical and Geoenvironmental Engineering, 2022
Liquefaction assessment has primarily been performed using in situ penetration testing, but this practice has become problematic for gravelly soils. For example, standard penetration test (SPT)- or cone penetration test (CPT)-based correlations can become unreliable owing to interference with large gravel particles, while the Becker Penetration Test ...

A method for the collection of soil monoliths from stony and gravelly soils

Geoderma, 1999
Monolith collection of soils with large amounts of coarse fragments, or of wet soils, pose specific problems which are directly related to their lack of physical stability. The purpose of this paper is to outline a procedure for soil monolith collection which is highly appropriate for these cases.

On the uniaxial compression strength of frozen gravelly soils

Cold Regions Science and Technology, 2020
Abstract Frozen gravelly soils are often encountered in both cold regions engineering and urban underground constructions by artificial freezing method. This work takes a gravelly sand in Beijing as the basic material. Gravel grains of 10–20 mm in size are obtained and mixed with sand grains at certain ratios and then saturated frozen samples are ...

Characteristics of Gravelly Soil Liquefaction in Wenchuan Earthquake

Applied Mechanics and Materials, 2011
Liquefaction of sand soil such as silty sand was quite popular in earthquake. Gravel liquefaction, by contrast, was seldom. Soil liquefaction was popular in Chengdu Plain in Wenchuan Earthquake and there was ejeched gravel in several sites. Through drilling and tests for typical liquefied sites, the study on distribution of layers, compactedness ...

Triaxial Shear Tests on Pervious Gravelly Soils

Journal of the Soil Mechanics and Foundations Division, 1956
Tests to determine shear characteristics of free draining gravelly soils; relations between shear resistance and density, amount of gravel, gradation, maximum particle size, and particle shape; effect of testing speed on shear test data and effect of specimen size for any maximum particle size up to 3 in.
