Buried pipes are
subjected to uplift loads, under certain circumstances such as earthquake-induced
faulting, urban excavations, high internal pressure caused by explosion and
offshore slope failures. Reliable design of buried pipes against these effects
requires the uplift capacity to be estimated. 
In this study, a laboratory model-scale investigation has been carried
out to determine uplift capacity of buried pipes in sand. The results of
laboratory model-scale tests designed to investigate the influence of the embedment
ratio of pipe and the density of sand on the uplift capacity of buried pipes
are presented. The results show that the uplift capacity is affected
substantially from pipe embedment ratio and density of sand.
