FAILURE LOADS OF VERTICAL ANCHOR PLATES IN SAND

In this discussion, one phase is reported of a detailed investigation on load deformation characteristics of vertical and horizontal anchor plates under various inclinations of pull. In the experimental study on vertical anchor plates under horizontal pull in dry sand under two- dimensional conditions, tests have been carried out on steel anchor plates of different sizes: 2.5 cm, 5.0 cm, 7.5 cm and 10.0 cm. The plates were embedded at various depths to achieve embedment ratios ranging from 1.5 - 14.5. Two different states of packing sand were used. Anchor plates were subjected to horizontal pull only. A continous record of horizontal pull versus displacement was maintained and load-displacement curves, from which the pull out loads have been computed, were plotted. The test data have been analyzed to study the variation of force coefficient for various embedment ratios. The plot of the results indicate that in the range H/h ratios up to 5, the force coefficient increases rapidly with the increase in H/h ratio, wheras beyond an H/h ratio of 5 the increase in the rate of increase of force coefficient is considerably reduced. It probably approaches a constant value at larger values of embedment ratio. In all tests with embedment ratios less than 5, the failure surfaces reached the top of fill, and these were termed shallow anchors, wheras in anchors with embedment ratios greater than 5, termed deep anchors, the rupture surfaces did not reach the top of the fill. The trends reported here are practically the same as those reported by the authors.
