Jacket Pack Anchor(JP Anchor) is applied the irregular layer that general ground anchor is difficult to be applied such as soft layer(standard penetration N value of less than 20) or gravel layer that grout lost. It makes sure of the pullout resistance required in these layers by the certain grout bulb formation and expansion effect. Thereby, Jacket Pack Anchor that is a new concept makes possible the construction improving and the cost saving in the excavation site. From the field test results, it was observed that the pullout resistance of Jacket Pack Anchor is about 84% greater than that of general ground anchor, and plastic deformation of Jacket Pack Anchor compared to that of general ground anchor is about 35% at the same load cycle. Especially, it was showed that the increase of resistance over 200% and plastic deformation is about 17% in gravel layer. This method has been applied mainly in the soft reclaimed soil and marine deposit areas of Inchon and Pusan etc. or in the loose layer of urban waste landfill. From the result of these cases, its usefulness has been proved because of ground displacement and building damage with little during the excavation work. Therefore, we propose strongly to try Jacket Pack Anchor in the past difficult layer from this paper. Also, we are hoping to take the full advantage of ground anchor that is secure enough workspace to minimize disturbance of excavation or underground structure can improve work efficiency, using Jacket Pack Anchor in the excavation site.
