✦ Synopsis

Prediction equations are developed and evaluated to estimate the maximum sustainable pull and the form of penetration of land anchors . The theories for estimating the pattern of penetration and maximum sustainable anchor force compare well with the measured results in five contrasting soil conditions . The maximum and mean error between the predicted and measured maximum anchor force were 13% and 8% , respectively , representing an over-prediction of force in both cases . The correlation coef ficient between the maximum anchor force and the mean values of soil shear strength , obtained using the cone index and shear vane were 0 и 86 and 0 и 85 respectively indicating that both the cone penetrometer and shear vane are valuable for in-field prediction of maximum anchor forces in both dry frictional and plastic clay soils .
