To investigate the ultimate uplift capacity of bell-shaped anchor with geotextile ties embedded in sand and to evaluate its breakout factor (Fqr), a series of 2-dimensional axisymmetric finite element analyses have been performed. Seven types of bell-shaped anchors with varying bell diameters ranging from 0.125 to 2.0 m were used in the analyses. From the results obtained through the analyses, it is found that with increase in the length of ties (Lg) to bell diameter (D) ratio, the breakout factor of anchor attached with the tie increases irrespective of embedment depth of anchor to bell diameter ratio, angle of internal friction (ϕ), and number of ties (N). The optimum values of Lg/D ratio and N were found to be 3 and 2, respectively. The maximum utilization of tensile strength of geotextile ties was around 62%. Fqr was highly influenced by scale effect. Based on the results of numerical analyses, a non-linear explicit model has been developed to evaluate the breakout factor of the anchor with ties installed in sand (Fqr) in terms of breakout factor of anchor without ties embedded within sand (Fq), H/D, (Lg/D), N, and friction efficiency (Ef).
