Experimental Investigation of Uplift Capacity of Buried Pipes

Abstract

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.
