Articles in Press, Accepted Manuscript, Available Online from 08 October 2021


  The interaction between an internal hole and two surrounded joints under a uniaxial compression are examined using the experimental and discrete element procedures. Inside the concrete sample, two notches and an internal hole are created. The joint angle change from 0° to 90° with an increment ...  Read More

Influence of Single Tunnel and Twin Tunnel on Collapse Pattern and Maximum Ground Movement

V. Sarfarazi; K. Asgari

Volume 13, Issue 1 , January 2022, , Pages 117-128


  Particle Flow Code in Two Dimensions (PFC2D) was used in order to examine the influence of single tunnel and twin tunnel on the collapse pattern and maximum ground movement. Since first PFC was calibrated by the experiments, the results obtained were rendered by a uniaxial test. Further, a rectangular ...  Read More

Effect of Confining Pressure on Is(50) Obtained by Point Load Test

V. Sarfarazi; K. Asgari

Volume 12, Issue 4 , October 2021, , Pages 1019-1028


  In this investigation, the impact of confining pressure on the tensile strength obtained by point load test (PLT) is examined by particle flow code in two dimensions. In this regard, at first, a numerical model is calibrated using the Brazilian experimental test results. The tensile strength of the model ...  Read More

Interaction between Tunnel and Surface Foundation using PFC2D

V. Sarfarazi; K. Asgari; Sh. Mohamadi Bolban Abad

Volume 12, Issue 3 , July 2021, , Pages 785-798


  In this work, we investigate the interaction between tunnel and surface foundation in two dimensions by the particle flow code. At the first stage, the PFC calibration is conducted using the experimental test results rendered by a biaxial test. Then the simulation of a biaxial test is performed by confining ...  Read More

Study of Rock Pillar Failure Consisting of Non-Persistent Joint using Experimental Test and Fracture Analysis Code in Two Dimensions

V. Sarfarazi; H. Karimi Javid; K. Asgari

Volume 12, Issue 1 , January 2021, , Pages 163-179


  The experimental and numerical methods were used to investigate the effects of joint number and joint angle on the failure behaviour of rock pillars under a uniaxial compressive test. The gypsum samples with dimensions of 200 mm × 200 mm × 50 mm were prepared. The compressive strength of ...  Read More
