Numerical Simulation of Piled-Raft Foundation in Cohesionless Soil using ABAQUS

Zehra Khan; Abhishek Sharma

Volume 14, Issue 4 , October 2023, , Pages 1183-1203

https://doi.org/10.22044/jme.2023.13324.2448

Abstract
  Due to rapid growth in infrastructure sector, the construction of high-rise buildings is becoming very popular among all the countries. Engineers face significant issues with high rise buildings, particularly in terms of structural and foundation aspects. Many old design approaches can't be used with ...  Read More

Experimental Investigation on Deformation Behavior of Circular Underground Opening in Hard Soil using a 3D Physical Model

Jinwei Fu; Mohammad Reza Safaei; Hadi Haeri; Vahab Sarfarazi; Mohammad Fatehi Marji; Leige Xu; Ali Arefnia

Volume 13, Issue 3 , July 2022, , Pages 727-749

https://doi.org/10.22044/jme.2022.12158.2213

Abstract
  In this work, the mechanical behavior of strata deformation due to drilling and surface loading is investigated using a 3D physical model. For this purpose, a scaled-down physical model is first designed. Then the tunnel drilling and support system are built. The subsidence experiments performed due ...  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

https://doi.org/10.22044/jme.2021.11088.2085

Abstract
  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

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

https://doi.org/10.22044/jme.2021.10846.2057

Abstract
  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

Interaction of Excavated Tunnels by Earth Pressure Balance Machines and Sub-surface Obstacles; Case Study: Tehran Metro Line 7

D. Mohammadi; K. Shahriar; D. Parsapour

Volume 12, Issue 3 , July 2021, , Pages 799-814

https://doi.org/10.22044/jme.2021.10868.2061

Abstract
  Tunneling in urban areas has always encountered many uncertainties, which if not considered in both analysis and design of the tunnels, will cause unexpected events during tunnel construction. Obstacles are among the most remarkable uncertainties in tunneling that affect the tunnel construction process. ...  Read More

Semi-Analytical Study of Settlement of Two Interfering Foundations Placed on a Slope

H. Haghgouei; A. Reza Kargar; M. H. Khosravi; M. Amini

Volume 12, Issue 2 , April 2021, , Pages 457-470

https://doi.org/10.22044/jme.2021.10509.2001

Abstract
  In many engineering constructions, the foundations should be built adjacent to each other. Therefore, the effect of interfering of close foundations should be considered in the design stage. In this research work, the effect of interference of closely separated foundations resting on a slope on the elastic ...  Read More

Numerical Modelling of Backfill Grouting Approaches in EPB Tunneling

L. Nikakhtar; Sh. Zare; H. Mirzaei Nasir Abad

Volume 11, Issue 1 , January 2020, , Pages 301-314

https://doi.org/10.22044/jme.2020.9155.1805

Abstract
  One of the main issues involved during tunnel construction with tunnel boring machines is the tail gap grouting. This gap is between the external diameter of tunnel lining and the excavation boundary that is filled with high-pressure grouting materials. In this work, three different approaches of gap ...  Read More
