The elastic response of multiple underream anchors

A technique to analyze multiple underream anchor systems resting in an elastic was developed. The approach is analytical and involves only a fraction of the computation required for a finite element analysis. The effects of anchor deph and inclination to the soil surface, and the spacing and number of underreams upon the elastic response of anchor systems are considered. A simple, approximate method for estimating the response of multiple underream anchors is proposed. This approach uses several interaction charts, which can be used as a hand method quite general anchor systems to sufficient accuracy for most practical purposes.
