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

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.

"Soil liquefaction: When solid ground turns into a liquid-like state during seismic activity. Soil liquefaction occurs when a cohesionless, saturated, or partially saturated soil substantially loses strength and stiffness in response to applied stress, such as shaking during an earthquake or other sudden stress changes. During this process, the soil behaves like a liquid rather than a solid. Increased water pressure in the soil pores reduces friction between particles, causing the soil to lose its load-bearing capacity. This can result in severe damage to buildings, roads, and infrastructure, as the ground can no longer support them, leading to sinking or tilting. video rights : Respective owners DM for removal /credits #liquefaction #geotechnical #engineering #technology #civilengineering #engenharia #construction #civilconstruction #engenhariacivil

𝗦𝗼𝗶𝗹 𝗟𝗶𝗾𝘂𝗲𝗳𝗮𝗰𝘁𝗶𝗼𝗻 : A silent threat. 😱 This fascinating (and terrifying) video dives into what happens when saturated soil turns into liquid during an earthquake. 🤯 The consequences for buildings, roads, and entire communities can be devastating. Let's learn how to mitigate this risk together. #SoilLiquefaction #Earthquake #Construction #Safety #GeotechnicalEngineering 💻🌐

The importance of middigating the water ingress and knowing the ground your working in, fill your voids and consolidate the ground when needed. This could have been avoided using our products and solutions that MC-Bauchemie provides. #MC-Bauchemie Canada #tuneling #Mining #groundimprovement #groundconsolidation

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.

One of the reasons site investigations and considerations are important before starting any project👌
