Structural Interaction at Joints in Pipe-Jacked Tunnels

When driving tunnels by pipe-jacking, relatively compressible packing material distributes the load of the jacking force at joints between pipes to reduce the risk of excessive local contact stresses. Concentrated stresses usually occur where the tunnel excavation departs from the intended line, causing sudden changes in pipeline direction. R.F. Haslem
