Parametric study on uplift capacity of anchor with tie in sand

In the present investigation a series of model tests have been performed to study the effect of different governing parameters viz., relative density ( D r ) of sand, the ratio of embedment depth ( H ) of anchor to diameter ( D ) of bell of anchor, number of ties ( N ), the ratio of length of tie (...

Description
Summary:In the present investigation a series of model tests have been performed to study the effect of different governing parameters viz., relative density ( D r ) of sand, the ratio of embedment depth ( H ) of anchor to diameter ( D ) of bell of anchor, number of ties ( N ), the ratio of length of tie ( L g ) to diameter of bell of anchor, diameter of bell of anchor and friction ratio ( f = ψ/ϕ ) on uplift capacity of anchor with ties embedded in river sand. From the experiment, it is observed that with increase in H/D ratio the ultimate uplift capacities of anchor with or without ties increase. With increase in number of tie layers up to 2, the ultimate uplift capacity of anchor with ties increases. A non linear power model has been developed to predict the ultimate uplift capacity ( Q Rult ) of anchor with ties in terms of ultimate uplift capacity of anchor without tie ( Q UR ), D r , H/D ratio, N , L g / D ratio, and f .
