A Model Test on Buried Pipeline Crossing Xi'an Ground Fissures
The buildings on the ground and the pipelines underground, especially water supply pipes and gas supply ducts, can be destroyed by ground fissures in Xi'an City. In order to study the influence of Xi'an ground fissures movement to buried pipeline, using reinforced concrete and loess simulated as underground pipes and stratum, two sets of large-scale physical model tests (1:5) on buried pipe cross-ground fissure were conducted with settleable test platform simulated as the movement of ground fissures. The difference between two tests is different setup when buried pipeline cross-ground fissures: one is opposite joint test setup and the other is straddle test setup. Test data and the damage of buried pipelines after the excavation were presented, and two failure modes are summarized. At the same time, there are differences in soil stress and damage between two pipelines when ground fissures moves. In order to avoid larger damage, opposite joint test setup is a better choice. This will have invaluable contribution to buried pipeline design of Xi'an.
