Can Tunnelling Cause Sinkholes and Are They Dangerous? Yes, tunnelling can cause sinkholes when soil is lost from above or ahead of a tunnel and a void migrates upward to the surface. These collapses can be hazardous to people, utilities and buildings, although large projects use monitoring and rapid ground treatment to reduce risk. In Melbourne’s Heidelberg, tunnelling on the North East Link has been paused while investigators examine a several metre wide hole on AJ Burkitt Oval that authorities say the nearby tunnel boring machines may have contributed to…

Can tunnelling trigger sinkholes? We unpack the risks, how tunnel boring machines manage ground loss, and what this means for projects like North East Link in Melbourne. #Melbourne #NorthEastLink #Sinkholes #TunnelBoringMachines #Tunnelling
