Abstract
The wide use of R.e. in hydraulic structures raised the problem of the effect of the uplift pres¬sures on such light structures. It became necessary to anchor such structures to the soil, otherwise massive floors may be added just to wi thstand the uplift forces.
Some structures may be subjected directly or indirectly to pull-up loads. Such type of structures
as pump stations, locks, dry docks, swimming pools ... ect needs anchoring to wi thstand flotaion. Other types
of structures as . transmission towers, retaining walls wi th back ties, anchor blocks, Penstocks etc need anchoring to withstand direct pull-up loads. For both cases the anchorages are the structural elements responsible to transmit the pull-up load to the soil
The shape of the anchor has been investigated as that for a disc, bulb, cruciform and bevelled type. In all cases, the investigators carried out their experiments on buried anchors, i. e., the anchor is fixed in posi tion inside the container in which the test is run and the soil, then, is placed in rammed layers according to a defini te technique to get the
