Abstract

An understanding of of Pressure acting on underground pipes, especially for buried pipes, tunnels and shafts, is often practical and necessary during design . The physical model involves a buried pipe installed in granular soil subjected to strip surface loading. The consequence of introducing a geogrid reinforcement layer above the pipe on the distribution of contact pressure is also survived.The results of laboratory investigations to measure the pressure on pipes have been investigated using tactile sensor technology. This method allows a continuous pressure profile to be measured around the pipes using flexible sheets. Geogrids or flexible sheets are used as reinforcement to improve the strength of soil or other materials. The numerical analysis is first validated using the experimental results and then used to investigate the comprehensive behavior soil -
