Investigation of the laboratory models scales in the analysis of the buried pipeline behaviors

For analysis the buried pipelines behaviors and recognition of interactions between the buried pipeline and the surrounded soil and real simulation and for recognition of sensitivity of parameters are in need of some experiments. Generally, researchers would use small laboratory models and in laboratory site with dimensional scales that included of variation of dimensional scales and some times the combination of the small models and site models is considered for the analysis of the parameters behaviors. For overtaking the high amount of parameters, finding the dimensional proportion from the site model is difficult that for preventing from these calculation difficulties, usually unit scale was considered and because in most scientific research the parameter effectiveness is important so the laborat ory models with regarded to the possibility power should prepare real conditions. In these articles besides introducing the laboratory models of underground pipelines, the site models, included of site models and laboratory models the variation gages model would be analysis according to the type of load or phenomena and purpose.
