In this investigation, silica fume (SF) was used as an additive material to study its influence on the characteristics of expansive soil. The soil in research prepared a lab by mingling bentonite (50 percent dry weight) with natural According (USCS), classified (CH) liquid limit 67.5 and plastic 29.3%. Expansive mixed different percentages (SF), (8, 9, 10, 11, 12, 13%), experiments were conduct...

The interaction of a building, its foundation and the underlying soils may have important effects on the behavior of each of these components as well as on the overall system behavior. For example, the relative stiffness of a building structure, its mat foundation and the soils that support the foundation will influence the stresses and displacements of both the structure and soil. Soil-structu...

A deeper understanding of the spatial variability of soil properties and the relationships between them is needed to scale up measured soil properties and to model soil processes. The object of this study was to describe the spatial scaling properties of a set of soil physical properties measured on a common 1024-m transect across arable fields at Silsoe in Bedfordshire, east-central England. P...

Measurements of the top surface vibration of a buried (inert) VS 2.2 anti-tank plastic landmine reveal significant resonances in the frequency range between 80 and 650 Hz. Resonances from measurements of the normal component of the acoustically induced soil surface particle velocity (due to sufficient acoustic-to-seismic coupling) have been used in detection schemes. Since the interface between...
