This paper evaluates the anchorage behavior of 29 shaft anchors installed in silty alluvial soil with two different types of tendon assemblies--singly anchored and multiple anchored. The full-scale test results reveal that the benefits of the multiple anchored anchor is less obvious for residual movement and ultimate anchorage capacity when compared with the traditional singly anchored anchor. A critical fixed length of 20 m is noted regarding the ultimate anchorage capacity for both singly anchored tension anchors and triply anchored compression anchors. The critical fixed length is substantially longer than the upper fixed length limit proposed by the major anchorage specifications. For anchors with fixed length shorter than the critical length, the anchorage capacity increases linearly with the fixed length. However, if the fixed length is extended beyond this critical length, up to 70 percent falloff in anchorage resistance per unit fixed length increment was observed.
