A TBM tunnel curve can raise settlement risk in soft ground by causing uneven stress, ground movement, and overcutting, increasing the chance of ground sinking.
Small radius makes micro tunneling feasible under highways by allowing precise navigation in tight spaces, reducing surface disruption, and maintaining road safety.
Curves can trigger retries on TBM machine steering, causing delays and equipment wear. Learn how proper planning and machine choice reduce these issues.
Small radius reduces permits for micro tunneling in cities by enabling safer, less disruptive installations and smoother approval for urban infrastructure projects.
