Abstract:
Buried pipelines as vital arteries,which will play a major role in human life should be designed and implemented in such a way that withstand the least possible harm with regard economic issues.In this study we tried to use a physical model, the impact of pipeline buried in soil slope under dynamic load are examined.To achive this goal we use a rigid metal bax with dimensions of 301.5*101.5*155 cubic meters for modeling. Pipes used in these experiments has a diameter of 1.6 cm which are connected by a fulcrum to the wall box. In order to measure strain generated in the pipe we use a series of strain gauges that were installed using the pipe at some points. Physical models made on Sharif University of Technology shaking table exposes to harmonic sinusoidal dynamic loading by 5Hz frequency. Determined by testing on various models for passing the pipe with 90 degrees to the direction of falling soil slope in the different burial depths, top of the slope is the most critical locations
