| Abstract: | This paper presents the results of experimental investigation on the effect of geotextile ties on uplift capacity of anchors
embedded in sand. Uplift capacity of anchor increases with increase in embedment depth to base diameter (H/D) ratio irrespective of type of anchor. With the introduction of tie to anchors, uplift capacity of anchors increases and
optimum number of layers of ties is found to be 2. A non linear power model has been developed to predict the uplift capacity
at any settlement (Q
R) of anchors with tie in terms of uplift capacity at any settlement (Q
URs) of anchor without tie, H/D ratio, number of layers of tie and displacement to base diameter ratio (Δ/D). The model is applicable for predicting Q
R having the values of Q
RS, H/D, N and Δ/D in the range of 0.257 ≤ Q
URs ≤ 1.420, 1.5 ≤ H/D ≤ 3.0, 1 ≤ N ≤ 4, 0.8 ≤ Δ/D ≤ 8. |
