Talk Title: Reflection and Refraction of Plane Waves in Saturated Poroelastic Layered Media / Scattering and Diffraction of Seismic Waves from an Arbitrary Shape Surface Topography and an Arbitrary Shape Embedded Structure
Abstract: Understanding the ground surface response due to deep or surface vibration sources at a given site is invaluable information to many engineering professions. For instance, estimating the surface disturbance at a anticipated construction site will help structural engineers design structures more effectively overcoming such disturbance that might not only have its effects on the structural integrity of the project, but also on its serviceability. Based on the assumption that the vibration takes place in a poroelastic layered media, a model relating vibration source along with layered media properties is proposed to present displacements, rotations, and stresses as the components of surface disturbance. By relating the effects of different layers properties (such as thickness, porosity, stiffness, saturation, etc.) a better understanding, as well as an estimation tool, of the ground surface response can be obtained ensuring more effective structural designs and a better occupants comfort.
