In general, polyethylene (PE), polyvinyl chloride (PVC), and ductile cast iron pipes are widely used in the water supply pipeline system. However, they have some disadvantages such as reduced durability due to material degradation, defects in connections, breakage of pipelines, and difficulties in continuous maintenance. To mitigate such problems, recently, research on durable and outstanding corrosion resistant glass fiber reinforced polymer plastic (GFRP) pipe is being actively conducted. GFRP is classified into the flexible pipe and when soil pressure and live load act on buried GFRP pipe, the load acting on the pipe is transferred to the surrounding soil. So, it should review the structural behavior and interaction between buried pipe and its surrounding soil because pipe will support the load with the surrounding soil together at the same time. To apply GFRP pipe for the water supply pipeline system, the structural reliability of GFRP water supply pipe buried underground should be investigated by examining the mechanical properties of GFRP pipe as well as the soundness of the pipe under buried state. The field test of buried pipe is conducted and the results are analyzed and discussed.
