Geotechnics & Tunnels Lab
GUTEC University Advanced Geotechnical Engineering, Underground Works, and Geotechnical Risk Laboratory
The Geotechnics & Tunnels Lab is the GUTEC University laboratory dedicated to soil engineering, soil and rock mechanics, geotechnical design in urban environments, and the planning, execution, and rehabilitation of underground works. Its mission is to train specialists capable of working safely and with technical expertise in one of the most demanding fields of engineering: that which occurs below the surface, where uncertainty is high, risk is real, and decisions must be supported by models, instrumentation, experience, and technical governance.
This laboratory is not limited to calculation or theory. It is a space for applied research, technology transfer, and professional training, where geotechnics is understood as what it truly is on site: a discipline of risk management, data interpretation, real-time decision-making, and multidisciplinary coordination.
GUTEC University, as a global private university with its own training and international agreements, conceives this laboratory with an international and practical approach, adapted to both infrastructure and urban rehabilitation: complex foundations, underpinning, micropiles, diaphragm walls, deep excavations, slope stability, NATM/TBM tunnels, waterproofing, drainage, auscultation, and back-analysis.
Why this laboratory exists: the terrain determines the project.
In many projects, the greatest technical and economic risk is not in the superstructure: it is in the ground, in its behavior, in its variability, and in how it interacts with the work. A geotechnical report interpreted superficially, an insufficient campaign, a poorly calibrated hypothesis, or an oversized support system can cause delays, cost overruns, claims, safety failures, or, in the worst case, serious incidents.
Geotecnia & Túneles Lab was created to respond to this reality with a modern vision: today’s geotechnics must be predictive, instrumented, digital, and decision-oriented, not just based on calculation memory. That is why the laboratory integrates three pillars:
Modeling and design: hypotheses, parameters, constitutive models, and verification
Instrumentation and auscultation: measurement, interpretation, and control of actual behavior.
Geotechnical risk management: decisions, contingencies, alert criteria, and uncertainty governance.
The goal is to train professionals who not only know how to “calculate,” but also how to anticipate, control, and act with rigor in the field, with an approach consistent with international projects.
Mission of the Geotechnics & Tunnels Lab
The laboratory’s mission is to develop applied knowledge and train talent in geotechnics and underground works, creating methodologies, real-life cases, and tools that enable:
- reduce geotechnical uncertainty in the project
- increase safety in excavation and tunnels
- optimize soil support and treatment
- improve decision-making based on instrumentation
- strengthen the resilience of existing infrastructure through underpinning and rehabilitation
- transfer international best practices to teams and organizations
What makes this laboratory at GUTEC unique?
This laboratory stands out for its comprehensive approach, which covers the entire cycle of a geotechnical project: from soil investigation to observed behavior and adjustment. At GUTEC, geotechnical engineering is not conceived as a closed discipline in the office; it is conceived as an iterative process with data feedback, where design is validated with measurement and improved with learning.
In addition, the laboratory incorporates a cross-disciplinary vision that connects geotechnics with:
- structures (soil–structure interaction)
- Urban infrastructure and existing buildings (underpinning, consolidation)
- underground works (ventilation, safety, drainage)
- digitization (connected instrumentation, geotechnical twin, series analysis)
- Contract management and claims (geotechnical risk and technical evidence)
Esto lo convierte en un laboratorio clave para proyectos complejos, especialmente en entornos urbanos y en activos críticos.
Lines of applied research and technological development.
The Geotechnics & Tunnels Lab is structured along lines that reflect the real challenges of the international market.
Urban rehabilitation requires intervention without disrupting the life of the building or neighborhood. This line focuses on underpinning, micropiles, submuraciones, injections, consolidation, and reinforcement, with detailed analysis of:
pathologies associated with differential settlement.
interaction between foundation and superstructure.
construction restrictions in urban environments.
impact on adjacent buildings.
deformation control and warning criteria.
Methodologies are developed to decide on the most robust solution with the least impact, considering safety, cost, timeframe, and operability.
Deep excavations (basements, stations, screens, galleries) require highly controlled design. Here we work on:
diaphragm walls, sheet piling, secant piles, Berlin piles.
anchors and struts.
control of lateral movements and settlements.
influence on buried services and adjacent buildings.
construction sequences as part of the design.
The laboratory emphasizes that the construction sequence is part of the “structural system” of support, and that instrumentation is essential to avoid surprises.
This line addresses geotechnical treatments to increase bearing capacity, reduce settlement, improve permeability, or control risks. It includes:
jet grouting, columns, vibro compaction.
injections, cementing, resins.
improvements for foundations and excavation.
treatment quality control and on-site verification.
Selection criteria, design, and execution control are addressed with a practical engineering approach.
In linear infrastructures and urban environments, slopes are a constant source of risk. This line focuses on:
stability and failure mechanisms.
mitigation measures (anchors, drainage, mesh, walls).
real-time monitoring and warning systems.
data interpretation and safety thresholds.
The laboratory integrates geotechnical analysis with risk management and operational continuity.
Underground construction combines geotechnical engineering, structures, safety, and operation. This line works on:
excavation and support according to method (NATM, TBM).
bolting, trusses, shotcrete, segments.
convergence, deformation, and face control.
water management, drainage, and waterproofing.
ventilation, fire safety, and evacuation in tunnels.
rehabilitation and sealing of leaks in existing tunnels.
Design criteria are taught and, above all, how to adapt decisions when the actual terrain differs from what was expected.
Water is one of the major risk factors in underground structures. This line addresses:
hydrogeological characterization.
pore pressures, flows, and seepage.
drainage and pressure relief.
waterproofing and sealing systems.
typical pathologies in basements and tunnels.
preventive maintenance strategies.
The laboratory works on practical solutions aimed at durability and incident reduction.
We work with advanced modeling for soils and rocks, with an emphasis on hypothesis, calibration, and validation. The focus is not on “making models,” but rather on:
selecting the appropriate constitutive model.
defining parameters with criteria.
understanding sensitivity and uncertainty.
comparing the model with measurements (back-analysis).
using modeling for construction decisions.
This approach trains professionals to be able to technically defend decisions before construction management, clients, and auditors.
Instrumentation is no longer “something extra”: it is the nervous system of geotechnical works. This line forms in:
design of auscultation plans.
inclinometers, piezometers, extensometers, prisms, GNSS, vibration.
data acquisition, telemetry, and control.
trend and threshold analysis.
alert response protocols.
back-analysis to recalibrate parameters and models.
The goal is for professionals to know how to measure, interpret, and act, not just install sensors.
Laboratory infrastructure and learning environment.
The Geotechnics & Tunneling Lab is designed as a professional practice environment. Students work with:
- Real datasets or highly realistic cases of geotechnical campaigns
- Standard project reports and memoirs
- Numerical models with defensible hypotheses
- Excavation sequence simulations
- Auscultation scenarios with time series
- Cases of pathology and rehabilitation of underground structures
The experience focuses on developing judgment: students learn to justify parameters, design control strategies, and communicate risks clearly and professionally.
