Detection of soil compaction using seismic surface waves

Seismic Surface Waves

Numerical study of soil dynamic compaction using ABAQUS model

One of the most important methods of soil compaction is dynamic compaction, which is one of the oldest and economical methods of soil improvement up to great depths. This method is applied due to its many benefits, including its economic procedure to correct many kinds of soil. One of the most important issues that affect soil improvement methods is being economic. The three main method...

Seismic holes for controlling surface waves

The concept of controlling seismic waves is in progress and first full-scale experiments had confirmed the interest which we can have for this new axis of research. The possibility of imagining a seismic 2D or 3D metamaterial made of a grid of inclusions or empty boreholes in the soil, interacting with a part of the earthquake signal is becoming realistic. Here we show the dynamic response of a...

Experiments on seismic metamaterials: molding surface waves.

Materials engineered at the micro- and nanometer scales have had a tremendous and lasting impact in photonics and phononics. At much larger scales, natural soils civil engineered at decimeter to meter scales may interact with seismic waves when the global properties of the medium are modified, or alternatively thanks to a seismic metamaterial constituted of a mesh of vertical empty inclusions b...
