Resumen:
During the last decades, research activity related to underground explosions and their effect on buried
structures and structures located on or above ground level have progressively increased. The correct
evaluation of the effect of this type of explosion is very important for the design of protection
structures.
The action of buried explosions on soils and the resulting effect on structures is a strongly complex
physical problem. The results are significantly dependent on many parameters that include the amount
of explosive, the shape of the load, the explosion depth, soil type and properties, among others.
Recent advances in numerical simulation have allowed the modeling of underground explosions.
Although there are some papers related to this problem, the knowledge of the effect on buried
structures or structures located on the ground is limited to a few numerical results without
experimental validation or some isolated experimental observations.
The effect of underground explosions on buried structures or structures on or above soil surface is
numerically studied in this paper. Numerical simulation is performed with a hydrocode. Different
alternatives to model the soil are analyzed. The effect of soil model and parameters on blast wave
propagation is particularly studied. In the case of structures located above the ground the capability of
different numerical models to reproduce soil ejecta that impacts on structures is also studied.
The paper also compares the present numerical results with numerical values obtained by other
authors using different hypothesis. Numerical results are contrasted with experimental results
available in the specialized literature.
