Small scale laboratory model tests were conducted to investigate the uplift behaviour of plate anchors with geosynthethics, embedded at shallow depth in sand. Three different type of geosynthetics, namely, a woven geotextile, a needle punched non woven geotextile and a geocomposite consisting of a non woven geotextile layer sandwiched between two layers of Netlon Geogrid CE-121, were used in this investigation. The variables in the investigation were type of geosynthetics, its location and size and number of layers of geosynthetics . Based on this investigation, it is found that the ultimate uplift capacity of plate anchors can be increased significantly by the use of geosynthetics. Only one layer of geosynthetics just on the top of anchor plate is found to be most effective for enhancing the uplift capacity. However, the displacement required for peak uplift resistance to be mobilised is relatively large in case of anchors with geosynthetics as compared to that required for anchors alone.
