CAVITY SIZE EFFECTS ON PLATE ANCHOR CAPACITY

Abstract

Many reasons deform the cavity inside the soil. The reasons can be classified to two main reasons natural and artificial reasons. Natural reasons belong to the type of soil (It is usually due to materials that enter the formation of the soil and may be affected by natural factors). And artificial reasons due to human work inside the ground like old buildings. The size of these cavities effect on the capacity on structures and it can cause huge damages for the structures. Experimental study presents the effect of size of cavity on the capacity of the plate anchor. A scale model anchor plate embedded inside sandy soil in laboratory to study the behavior of it under the effect of three types of cavities with dimeter (10,15 and 20) cm. the results show direct effect on the capacity of plate anchor and the type of failure that deform inside the soil to resist the uplift loads.
