Development of the pipe cutting technology within utility tunnel

• • Pipe cutting technology within the utility tunnel has been developed for long-term maintenance & management

  • Three alternatives (waterjet cutter, laser cutter, and diamond wire saw) were compared under six evaluation citeria, using AHP

  • Ultimately, prototype of pipe cutting tool within the utility tunnel has been suggested

• • Experimental simulation of internal erosion mechanism leading to ground subsidence: Focus on suffusion, backward erosion

  • Investigation of monitoring techniques for internal erosion using electrical resistivity
