Abstract

Bearing capacity of anchor cables are influenced by numerous factors, with the proportion of fixed anchor length playing a critical role in both bearing performance and construction cost. However, previous studies have often overlooked the significance of this parameter. In this paper, numerical simulations are employed to explore the effect of the fixed anchor length proportion on the bearing capacity and failure modes of anchor cables. Simulations were conducted for anchor cables with fixed anchor length ratios of 1, 0.9, 0.85, 0.8, 0.75, 0.7, 0.65, 0.6, 0.55, and 0.5 under identical burial depth conditions. The results reveal that when the fixed anchor length proportion exceeds 0.75, the bearing capacity initially increases and then stabilizes with further increases in the ratio. This trend is consistent with the behavior observed when the ratio is below 0.75. However, the failure patterns differ between the two cases. For fixed anchor length proportions greater than 0.75, the failure pattern manifests as an “inverted cone” extending to the ground surface, whereas for proportions less than 0.75, the failure pattern is “ellipsoidal,” without surface extension.
