A method to predict the load-displacement relationship of ground anchors
According to results from measurements of stress obtained by tests of the ground anchor, the relation between skin frictional stress of the anchorage bulb and its displacement is non-linear, and the axial force distribution range of the anchorage bulb expands gradually towards the tip due to increase of the load.
In order to explain such behavior of the ground anchor, we have proposed a formula, which gives the load-displacement relationship of the ground anchor, by assuming an elasto-plastic model of skin frictional stress-displacement relation at a point on the anchorage bulb. Moreover, in order to apply this formula to actual cases, we have analysed numerous data from anchor tests conducted on the site and we have examined the load-displacement relationship, the distribution of axial force, and various ground constants included in the formula. As a result, we have found out a mutual relationship between the ground contants and the N value of the standard penetration test.
Therefore, if N value is given as result of the soil investigation, it will be possible to predict the load-displacement relationship of the ground anchor.
