Embedded Anchor Response to uplift Loading

A number of factors which influence soil-anchor interaction are evaluated, and in addition, the extent of soil disturbance and the influence of pore water pressures during testing are assessed. Response under repeated and sustained-repeated loading is shown to be represented by a family of hyperbolic curves, and a failure criterion is determined by the critical strain condition below which a satisfactory response can still be subsequent to repeated loading. A strain dependent mechanism is used for defining behaviour under varying loading conditions which permits an assessment of anchor life when subjected to a package of projectd environmental conditions. Where possible the results are compared to those of other workers in the anchor field, and recommendations made which may lead to a better understanding of embedded systems.
