Aging effects on liquefaction resistance of sand estimated from laboratory investigation

open access: yesSoils and Foundations, 2023
Liquefaction resistance is known to increase concomitantly with the increase in time after construction or sedimentation. Nevertheless, the mechanisms of its aging effect on liquefaction have not been completely elucidated.

TRIAXIAL COMPRESSIVE STRENGTH OF ULTRA HIGH PERFORMANCE CONCRETE

open access: yesActa Polytechnica, 2013
The aim of this work is to describe the strength of Ultra High Performance Concrete (UHPC) under triaxial compression. The main goal is to find a trend in the triaxial compressive strength development under various values of confinement pressure.

Effects of particle size and confining pressure on breakage factor of rockfill materials using medium triaxial test

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2016
Rockfill dams are mostly constructed using blasted rockfill materials obtained by blasting rocks or alluvial rockfill materials collected from the riverbeds.

Calculating the state parameter in crushable sands [PDF]

open access: yes, 2019
The state parameter (y) measures the distance from the current state to the critical state line (CSL) in the compression plane. The existence of a correlation between both the peak angle of shearing resistance ( # $ ) and peak dilatancy and y is central ...

Strength Characteristics of Nonpenetrating Joint Rock Mass under Different Shear Conditions

open access: yesAdvances in Civil Engineering, 2020
The mechanical property of jointed rock mass is an important factor to be considered in the analysis, evaluation, and design of actual rock engineering. The existence of joints threatens the stability and safety of underground engineering projects built ...

Determination of the Internal Friction Angle of Gravel based on the p-q Graph for Direct Shear Tests [PDF]

open access: yesرویکردهای نوین در مهندسی عمران, 2018
Since its simplicity and availability, direct shear test is a current one. This test, compared to the triaxial test, provides different values for the parameters of the gravel due to the specific shape of the test device and the test approach.
