DEEPSOIL is a specialized engineering software program for modeling the propagation of seismic waves through soil layers.

It was developed by Professor Youssef Hashash’s research group at the University of Illinois, USA. The program is intended for specialists in earthquake-resistant construction and geotechnical engineering.

With DEEPSOIL, you can

- Simulate earthquakes: calculate how seismic waves propagate from the lower soil layers to the surface.

- Account for soil nonlinearity: changes in soil stiffness and damping during strong vibrations.

- Calculate pore pressure: simulate its changes under seismic loading, including the associated processes in the soil.

- Perform linear and nonlinear analyses in the time and frequency domains.

- Generate graphs of accelerations, velocities, displacements, and response spectra at various depths.

What is its practical application?

For example, consider a site designated for building construction. Geologists have determined that the top layer consists of soft clay, followed by sand, and then dense soil at greater depths.

DEEPSOIL allows you to assess how an earthquake originating from below will change as it passes through these layers and what vibrations will occur directly at the surface.

This is important for calculating seismic effects on buildings and structures.
