Soil liquefaction is a geotechnical phenomenon that occurs when saturated soils lose their load-bearing capacity due to vibrations or seismic activity. This is common in granular soils, such as loose sands or gravels, where the water between soil particles cannot escape quickly enough, causing the soil to behave like a liquid. When liquefaction occurs, structures built on these soils can experience displacement, sudden settlements, and even collapse due to the loss of support in the foundations. This effect is especially dangerous in regions with high seismic activity. For liquefaction to occur, specific conditions must be present: the soil must be saturated, made of loose materials, and subject to dynamic loads or vibrations. The consequences of this phenomenon are devastating, affecting buildings, bridges, and other critical infrastructure. Geotechnical engineers implement ground improvement methods, such as compaction or drainage, to reduce the risk of liquefaction in susceptible areas. Preventing its effects is essential to ensure the safety and stability of constructions in seismic regions. #GeotechnicalEngineering #Liquefaction #SaturatedSoils #SeismicActivity #SeismicRisk #GeotechnicalPhenomena #StructuralSafety #Settlements #EarthquakePrevention #SafeInfrastructure #GroundImprovement #SoilStability #GranularSoils #CivilEngineering #SafeConstruction

🏗️ One of the first steps in planning any project is conducting an infiltration test, which measures how quickly water moves through the soil. For commercial, residential, or public projects, accurate infiltration testing is essential for effective stormwater management. By understanding how the soil handles heavy rainfall, you can design better drainage systems and avoid future structural issues. Conducting these tests across multiple points on your site provides a complete picture of water absorption, guiding safer, more resilient development. Soil compaction, water absorption, and other geotechnical factors are key to long-term project stability, making infiltration testing a crucial step in successful property planning. Infiltration testing is just one of the many services offered through our Drilling and Subsurface Exploration Consulting.

Flooding is a major ground risk in tunnel construction, as unexpected water ingress can destabilise excavation, delay progress, and endanger safety. Thorough ground investigation is essential to identify groundwater levels and potential water-bearing zones, allowing engineers to plan effective water control measures and reduce the risk of flooding. Probing ahead of the tunnel face is also a reliable method to detect potential water before excavation, enabling timely adjustments to tunnelling methods.

Flooding prevention during tunnel construction is critical to ensure both the safety of workers and the integrity of the project. Effective measures include conducting thorough hydrological studies to understand groundwater levels and flow patterns. Engineers often implement diversion systems, such as ditches or pumps, to redirect water away from the construction site. Additionally, waterproofing techniques and installing drainage systems within the tunnel structure can mitigate the risk of water ingress. Regular monitoring of weather conditions and water levels is also essential, allowing for proactive adjustments to construction plans and methods. Together, these strategies help manage water-related challenges, ensuring a safer and more efficient tunnel construction process.

Flow Failure of “La Luciana” Tailings Storage Facility (Tsf) Due to Seepage (Spain, 1960) This study analyzes the 1960 flow failure of the “La Luciana” tailings storage facility (TSF) in Reocín, Cantabria, Spain, which resulted in 18 fatalities. This disaster is the most significant in terms of loss of human lives in Spain during the 20th century. Geotechnical and hydraulic tests defined the tailings' types and spatial distribution. -Aldo Onel Oliva González, Joanna Butlanska, José Antonio Fernández Merodo, Roberto Rodríguez Pacheco https://lnkd.in/gCy9miUK #Tailings  #tailingsdam #tailingsstoragefacility #TSF

🚨 Flooding in Tunnels: Challenges, Causes, and Prevention 🚨 Flooding in tunnels is a growing concern for infrastructure resilience and public safety. From transportation hubs to utility passages, flood risks are amplified by extreme weather events and inadequate drainage. Here’s a quick dive into the causes, impacts, and ways to keep tunnels safe and dry: 🔍 Key Causes: 1️⃣ Extreme weather (storms, heavy rainfall) 2️⃣ Poor drainage design or maintenance 3️⃣ Rising groundwater levels 4️⃣ Nearby water bodies (rivers, seas) 5️⃣ Structural failures or water main breaks ⚠️ Impacts: Infrastructure damage and costly repairs Electrical system and operational disruptions Serious safety risks for occupants 🛠️ Prevention & Mitigation: Advanced drainage and regular maintenance Waterproofing tunnel linings and sealing cracks Installing flood barriers and gates Automated pumps and remote monitoring Emergency preparedness and evacuation planning With climate change driving more extreme weather, proactive flood management in tunnels has never been more critical. By investing in resilient design and tech-driven monitoring, we can protect our tunnels and ensure their safety for years to come! #Infrastructure #FloodManagement #TunnelSafety #CivilEngineering #Resilience #civil

Water control: Excess water can lead to flooding, making areas unsafe for workers and machinery. A proper dewatering plan ensures areas remain safe and accessible, preventing accidents and hazardous conditions.
