Centrifuge Modeling of an Underground Structure Subjected to Blast Loading

In this paper, first, the principles of physical modeling in geotechnical centrifuge has been explained and then, the application of these principles in modeling of the blast loading is described. Thereafter, procedures and equipment of a blast test in IUST centrifuge are described. Results are presented in the form of acceleration, stress and strain time histories for two different points of underground structures that is located in the depth of 5.6 meters from ground surface. It is observed that the results are in good agreement with existing codes and past researches. The results of this study can be used to investigate the effects of blast loading on underground structures and verification of softwares to more extensive studies.
