Soil-Structure Interaction of Buried Pipes Under Cyclic Loading Conditions
The safety of lifelines, as the most important urban facilities, under different conditions highly depends on the safe design and performance of these buried structures. This cannot be achieved unless their actual behaviors are well understood and considered at the designing stage. A new physical model was developed in Amirkabir University of Technology to study the behavior of buried pipes und...
متن کاملuplift response of buried pipes in saturated sand using finite element method
in this research a numerical analysis using plaxis program has been carried out to investigate the behavior of buried concrete box culverts different parameters including load types, loading locations, culvert dimensions, underlying soil specifications, and the coefficient of earth pressure- at- rest. for modeling purpose, patch loading of rtuck or military tank has been substituted to an equiv...
متن کاملThe impact of shallow cover on tunnelling in soft soil
Shield tunnelling is used widely in constructing underground infrastructure in cities due to the ability to limit settlements and damage to existing buildings. However, in an environment with soft overburden and buildings on pile foundations, the tunnel is often designed well below the pile tip level. There are two reasons for doing this: to reduce interaction between tunnelling process and pil...
متن کاملFinite Element Analysis of Pipe Buried in Saturated Soil Deposit Subject to Earthquake Loading
A coupled stress-flow finite element procedure, based on dynamic Biot equations, was used to analyze the behavior of pipe buried in liquefiable soil. The governing equations, soil constitutive model, finite element discretization and solutions were described. The results of analysis were compared with two cases of dynamic centrifuge test of soil deposit and pipe conducted at 30-g acceleration f...
متن کاملUplifting Behavior of Shallow Buried Pipe in Liquefiable Soil by Dynamic Centrifuge Test
Underground pipelines are widely applied in the so-called lifeline engineerings. It shows according to seismic surveys that the damage from soil liquefaction to underground pipelines was the most serious, whose failures were mainly in the form of pipeline uplifting. In the present study, dynamic centrifuge model tests were conducted to study the uplifting behaviors of shallow-buried pipeline su...
