Buried pipes aresubjected to uplift loads, under certain circumstances such as earthquake-inducedfaulting, urban excavations, high internal pressure caused by explosion andoffshore slope failures. Reliable design of buried pipes against these effectsrequires the uplift capacity to be estimated.In this study, a laboratory model-scale investigation has been carriedout to determine uplift capacity of buried pipes in sand. The results oflaboratory model-scale tests designed to investigate the influence of the embedmentratio of pipe and the density of sand on the uplift capacity of buried pipesare presented. The results show that the uplift capacity is affectedsubstantially from pipe embedment ratio and density of sand.
