Evaluation of Deformation Behavior of Sand-Clay Mixture under Traffic Loads
(AMER SOC CIVIL ENGINEERS, UNITED ENGINEERING CENTER, 345 E 47TH ST, NEW YORK, NY 10017-2398 USA, 2020)
Vehicle traffic loading induces a heart-shaped stress path in deviatoric stress space [tau z theta to (sigma(z)-sigma(theta))/2], causing the rotation of principal stress direction acting on a soil element. A conventional ...
Effect of principal stress rotation on deformation behavior of dense sand-clay mixtures
(TAYLOR & FRANCIS LTD2-4 PARK SQUARE, MILTON PARK, ABINGDON OR14 4RN, OXON, ENGLAND, 2021)
This paper investigated the deformation behaviour of K-consolidated sand-clay mixtures through cyclic triaxial (CT) and hollow cylinder (CHC) tests. The sand-clay mixtures contained 0%, 5%, 10% and 20% clay by weight and ...
Deformation characteristics of medium-dense sand-clay mixtures under a principal stress rotation
(ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2021)
A moving wheel load induces a principal stress rotation (PSR) in pavement foundation geomaterials including subgrade/subbase soils. Simulating such a stress condition is not possible with stress path tests conducted with ...
