This video highlights the risks of tunnelling in poor ground conditions, highliting the critical need for thorough ground investigations before construction and continuous probing ahead of the tunnel during excavation. The construction method should be carefully chosen based on geological conditions and risks, with proactive ground stabilisation measures implemented where necessary. Tunnelling is essential for development, but its associated risks must be thoroughly understood, and mitigation measures should be developed before the construction stage.

The importance of middigating the water ingress and knowing the ground your working in, fill your voids and consolidate the ground when needed.

Before tunneling is done, a complete stability analysis has to be carried out and approved during mine planning, the an appropriate method can be used and the amount and type of support needed ascertained.

Tunnel excavation is a crucial component of almost all significant public transit projects. Companies in various countries rely on ShapeArray to track changes in convergence and subsidence while constructing tunnels in difficult geological environments.

Reflections on Tunnel Collapse: Causes and Lessons this is a video of a tunnel collapse during construction, and it’s a sobering reminder of the complexities and challenges we face in our field. The video outlines several key reasons for such failures: Geological Instability: Weak or fractured rock formations can lead to serious stability issues. Engineering Shortcomings: Poor design or inadequate support systems can compromise the tunnel’s integrity. Material Quality: The use of subpar or deteriorating materials can be a major factor. Natural Disasters: Events like earthquakes and floods can disrupt even the most well-planned projects. Human Error: Mistakes in planning, execution, or maintenance can significantly contribute to failures. These points underscore the critical need for rigorous inspections, advanced monitoring, and adherence to strict safety protocols. As professionals in the field, it’s crucial for us to learn from such incidents and continuously improve our practices to ensure the safety and reliability of our projects. It’s a reminder of how vital our role is in safeguarding infrastructure and the importance of never becoming complacent.

Tunnel collapses....reasons Tunnel collapses can result from geological instability, poor engineering, or inadequate construction materials. Geological factors include weak or fractured rock formations, leading to instability and eventual collapse. Inadequate design, such as improper support systems or insufficient reinforcement, can compromise tunnel integrity. Construction materials that deteriorate over time due to environmental conditions or subpar quality may contribute to collapses. Natural disasters like earthquakes and floods also pose significant risks. Human error, whether in planning, execution, or maintenance, can amplify these issues. Regular inspections, advanced monitoring systems, and strict adherence to safety protocols are crucial to preventing tunnel collapses and ensuring the longevity and reliability of underground infrastructure. video rights : Respective owners DM for removal/rights #tunnelling #tunnel #tunnelconstruction #engineering #civilconstruction #civilengineering #construction #engenharia #engenhariacivil #mechanicalengineering

By understanding the various slope failure mechanisms, we can develop effective strategies for prevention and mitigation. Let's delve into the complexities of slope stability and explore how we can protect lives and property. #Geoscience #GeotechnicalEngineering #SlopeAnalysis #SlopeStability #Landslides #Infrastructure #Safety 🌐 💻

The demolition of outstanding detonators in a tunnel is generally not allowed based on regulations due to the confined space, which significantly increases the risk of structural damage, entrapment, and uncontrolled explosions. Regulations typically require detonations to occur in open or specifically designed and controlled environments to ensure maximum safety and containment of the blast. Exceptions might exist only under stringent conditions and with specific safety measures and approvals from relevant authorities. We have covered the drill and blast method along with all other tunnelling methods in our Online Tunnel Engineering course. Register for the course today and elevate your knowledge and skill.

A geotechnical survey involves the investigation of the physical properties of soil, rock, and subsurface conditions at a particular site. This information is essential for designing and constructing buildings, roads, bridges, dams, and other infrastructure to ensure safety, stability, and longevity. It is one of the first and essential steps carried out before structures are built to come up with the soil properties and characteristics.
