Underground flexible pipes for electric cables are subject to external loads and surrounding soil pressure. Particularly, strain of flexible pipes is of great concern in terms of safety and maintenance of electric cables. In this paper, stress and strain of flexible pipes with two types of installation gap, ie, l0cm and naught, were compared to investigate the structural integrity of pipes from actual field test. The effect of degree of compaction and burial depth were also investigated to simulate the variety of construction situation. The results of the field test show that the strain criteria were satisfied under the burial depths of 80cm, 100cm and 120cm regardless of installation gap.
