Hatch
- Analyzed tunnel convergence using FLAC3D software under open or closed modes of excavation
- Analyzed tunnel lining under different combinations of dead load, internal and external hydraulic loads and Time-Dependent Deformation (TDD),
- Calculated sustainable TBM thrust load on each PCTL ring by simulating applied shoe pad loads on circumferential joints.
- Performed Unwedge analysis to define rock wedge load on tunnel lining
- Reviewed tunnel lining drawing to be in compliance with design assumptions and fundamentals.
- Evaluated load bearing capacity of tunnel radial joints under combination of axial load and joint rotation.
- Prepared tunnel lining report for Inner Harbour West Tunnel project.
- Calculated PCTL handling and stacking stresses for different patterns and layouts.
- Evaluated bolt and dowel capacity for circumferential and radial joints

Geotechnical Engineer -Dam specialist 2015-2019
Mahab Consulting Engineering Company, Iran
- Supervised subsurface explorations and laboratory testing in the dam foundation area, reservoir, and surrounding areas not only for the design of the dam but to locate construction materials
- Prepared numerical modeling of Tehran subway station made in sequential excavation method (SEM) using FLAC2D
- Evaluated and interpreted laboratory and field test results and suggested geotechnical parameters (such as triaxial shear test, consolidation, swelling, and Compaction test …)
- Performed stability analysis using Geostudio software(limit equilibrium analysis)
- Carried out seepage analysis using Seep/W software and FLAC2D
- Performed static, pseudo-static, and nonlinear Dynamic analysis using FLAC2D software
- Assessed liquefaction potential of Foundations and performed post-earthquake analysis.
- Prepared technical reports for static and dynamic analysis and provided recommendations for foundation improvement when needed
- Collected instrumentation data (piezometers, inclinometers, downstream wells,..) and performed real-time numerical and limit-equilibrium analysis
- Conducted numerical analysis of tunnels and prepared GRC & LDP using Flac2D,3D
ACHIEVEMENTS - Successfully performed pseudo–static analysis of the highest earth-fill dam in Iran with seismic coefficient varying throughout the height of the dam. This was a first in Iran and greatly increased the company’s profile in the industry
