ABSTRACT
The pipelines' allowable settlement has rarely been mentioned in design references and codes. The present paper studies the effects of differential settlement of pipeline bed on resulted forces and deformations and then determines the allowable differential settlement of pipelines in two conditions as follows: (i) heterogeneous soil bed (ii) adjacent to reservoirs. Numerical simulation of pipeline is used in order to accomplish the studies. The pipeline bed is idealized by Winkler springs and four-element standard viscoelastic Burger model. Also, the use of geosynthetic reinforcement is studied in heterogeneous soil beds and the effect of geosynthetics on decreasing the settlement has been investigated.
