Protect Buried Pipe by Reinforcement Soil
Therefore, damage of these systems can result in heavy loss of functionality with the consequential interference to the economic and social recovery in the areas where the damage occurred and, also, at the end of the „lifeline‟, possibly allowing illnesses and epidemics to develop.
To further study the distribution of pressure on the buried structure and the soil-geogrid interaction, numerical analyses are performed using a multi-scale finite-discrete element framework that allows for both the explicit modeling of soil particles using discrete elements and the modeling of the embedded structure using finite elements. The numerical framework is first validated using the experimental results and then used to investigate the detailed behavior of the soil-pipe system.
Anderson, 1913). Geosynthetic application is one of the engineering solutions which employed to improve the behaviour of foundation beds [M. G. Spangler, 1941]. Although, some researchers have studied the pipe response in planar reinforced trench soil, but there is little literature studying the pipe behaviour in geocell reinforced trench subjected to surface loading.
