Soils are unique materials. Analogous to all other particulate materials, their properties depend on environmental parameters, such as confinement and fluid characteristics. While behavior of soils is complex, simple micromechanical analyses at the particle level provide unparalleled insight. Furthermore, elastic and electromagnetic waves can be effectively used to gain complementary information about the particulate medium, leading to unique possibilities for studies in engineering and science, including field applications for site assessment and process monitoring. This book is divided into five parts. The first part dwells on the problem of scale and includes a general introduction to materials. In the second part, the behavior of particulate materials is reviewed, with emphasis on the microscale interpretation of macroscale behavior. Fundamental differences between fine and coarse particulate materials are highlighted. The third and fourth parts center on the propagation of mechanical and electromagnetic waves in particulate materials, addressing phenomena such as stiffness, polarization and losses. These two units include laboratory techniques to measure the elastic and electromagnetic spectral response of particulate materials, and an extensive compilation of experimental data. Finally, the fifth part applies elastic and electromagnetic waves to monitoring processes in soils. Emphasis is placed on clear, simple analyses and explanations of complex physical phenomena, making this book ideal for self-study. Furthermore, no other book provides such an in-depth description of soils and their behavior and the interaction of elastic and electromagnetic waves with particulate materials (including material data and experimental methods). Thus, this is an invaluable reference for postgraduates, research scientists and practitioners in geotechnical, civil and environmental engineering, as well as scientists in related areas such as physics, geophysics and materials science.

When an earthquake occurs, some of the energy it releases is turned into heat within the earth. Some of the energy is expended in breaking and permanently deforming the rocks and minerals along the fault. The rest of the energy, which is most of the energy, is radiated from the focus of the earthquake in ... Shigaraki soil and Toyoura sand were used as soil samples in the experiments. The intensity of the reflected waves increased with the soil's water content and changed dramatically depending on whether the soil was fully dry, wet, or fully saturated.The propagation time decreasedas the groundwater level rose.This methodhas advantages in soi Soil erosion is many things but, it is mostly the washing away of soil by the elements. Soil is naturally removed by the action of water or wind. Other causes of soil erosion can be plowing ... "Soil temperature was on average 10 degrees hotter in heated plots than control plots, but water potential and soil water content were completely unaffected by heating. This tells us that the grasses died from reasons other than water stress- perhaps a top-kill effect." Although growing concern over heat waves in agriculture is centered around accompanying droughts, this experiment ... A mesoscale convective system (MCS) case study was observed over northeast Mali as part of the African Monsoon Multidisciplinary Analysis (AMMA) on 31 July 2006. Observations of this case suggest tha... Earthquake - Earthquake - Properties of seismic waves: At all distances from the focus, mechanical properties of the rocks, such as incompressibility, rigidity, and density, play a role in the speed with which the waves travel and the shape and duration of the wave trains. The layering of the rocks and the physical properties of surface soil also affect wave characteristics. [en] soil vibration ; soil waves ; waves decomposition: Abstract : [en] Man-made vibrations from different types of sources are usually measured on the surface of the ground or building. The measured signal is always the superposition of all travelling basic waves. For a homogeneous half space there are three basic waves - the Compressional (P-wave), Shear (S-wave) and Rayleigh wave (R-wave ... 1 Title of paper: Detection of soil compaction using seismic surface waves Names of authors: Shane Donohue1, Dermot Forristal2, and Louise Donohue3 Affiliation of authors: 1 School of Planning, Architecture and Civil Engineering, Queens University Belfast Soil‐structure interaction with Rayleigh waves Soil‐structure interaction with Rayleigh waves Gómez‐Massó, Alberto; Lysmer, John; Chen, Jian‐Chu; Seed, H.

Through the body of the Earth these are called P-waves (for primary because they are fastest) and S-waves (for secondary since they are slower). However, where a free surface is present (like the Earth-air interface) these two types of ... The strength and stiffness of concrete may be empirically determined from nondestructive methods by using elastic waves. Although the theoretical relationship between the elastic wave velocity and the strength or elastic modulus cannot be derived in a composite material, attempts have been made over the past sixty or more years to correlate the properties of composite materials with elastic ......
