Bored Tunnelling Ground Impact Assessment

Get started with your design

Bored Tunnelling Ground Impact Assessment is a specialized tool for predicting ground settlement and potential building damage due to bored tunneling activities. Using the method outlined in Burland et al.'s 1977 paper, Prediction of Ground Movements and Assessment of Risk of Building Damage Due to Bored Tunnelling, it estimates both short-term and long-term impacts on surrounding structures, allowing users to assess risk and design accordingly.

This tool is for:

• Geotechnical Engineers – requiring accurate predictions of ground movement to mitigate risk and inform design strategies for tunneling projects near existing structures.
• Structural Engineers – assessing potential impacts of settlement on building integrity, especially for projects in urban or sensitive environments.
• Urban Planners – evaluating the safety and feasibility of tunneling projects in densely populated areas, where infrastructure protection is crucial.

By offering a detailed assessment of potential impacts, this tool enables users to conduct comprehensive feasibility studies and support decisions that protect buildings from tunneling-induced settlement. This parametric technical document is essential for risk mitigation in design stages, improving project safety and long-term stability.

FAQs

Why is long-term settlement assessment important for urban tunneling projects?

Long-term assessments help evaluate risks to buildings from delayed settlement, ensuring safety and stability well beyond the initial tunneling phase.

What types of buildings are most at risk from tunneling-induced settlement?

Older, unreinforced masonry buildings and structures on shallow foundations are generally more vulnerable to damage from ground settlement.

Are there alternative methods to Burland’s approach for assessing ground impact?

Yes, other empirical and analytical models exist, but Burland’s method remains widely used for its practical balance between complexity and accuracy.
