MIDAS GTS NX

Next generation
geotechnical analysis
software

MIDAS GTS NX is the latest generation of software for geotechnical analysis based on the finite element method. MIDAS GTS NX is a multifunctional software for modelling the most complex geometries which is provided with the new 64 - bit solver enabling calculations with impressive speed. MIDAS GTS NX has a lot of practical functions which help user to create analysis output, reports, notes including 3D PDF standard. Intuitive interface which stand out the GTS NX MIDAS from the existing geotechnical FEA package, allows users to easily and quickly implement software in the design process.

Applications

Foundations:

• Shallow foundation: direct foundation, mechanic (vibration) foundation,
• Deep foundation (pier/abutment): pile (steel pipe, PHC, drilled shaft (RCD), driven pile), well foundation, caisson, raft foundation,

Excavation/retaining wall:

• Retaining wall: H-pile + slurry wall, sheet pile, CIP, SCW, D-wall,
• Strut: steel strut, earth anchor, rock bolt, soil nail, tie rod, raker,
• Stability analysis for adjacent structures,

Slope stability:

• Strength reduction method analysis (SRM): 2D / 3D SRM analysis, SRM analysis by construction stages, SRM considering rainfall, nonlinear dynamic analysis + SRM analysis,
• Stress analysis method (SAM): potential sliding surface + SRM, analysis consideration of rainfall/staged analysis,
• Evaluation of slope reinforcement: nail, rock bolt, stabilizing piles, retaining wall, evaluation of reinforcement stability in slopes reinforced by structural members,

Tunnel:

• Road tunnel: portal, cross passage, refuge area (emergency zones), ventilation shaft, electrical room, fault fractured zone, adjacent structures,
• Railway/subway tunnel: fitting (T, Y-type), shield TBM, machine room, TRcM/CAM, station,
• Steel pipe roof: steel strut, full face / bench cut, ring cut, CD cut, open cut, 2 arch, 3 arch,

Soft soil/embankment:

• Soft soil: SCP-reinforced, dewatering method (PBD, PSD, SD), suction drain,
• Embankment: revetment and quay wall, dock, breakwater,

Hydraulic/underground structure:

• Hydraulic structures: earth dam, CFRD, levee, water way tunnel (pipe & culvert),
• Underground structures: box, underground driveway.
