The analysis of building structure in contact with soil involves an interactive process of stresses and strains developed within the structure and the soil field. The response of Piled-Raft Foundation system to the structure is very challenging because there is an important interplay between the component of building structure and the soil field. Herein, soil-foundation-structure interaction of...
SoilEngineering is a user-friendly, interactive Microsoft Excel spreadsheet program for the geotechnical and geophysical analysis of soils. The influence of soil behavior on earthquake characteristics and/or structural design is one of the major elements in investigating earthquake forces, and thus the structural response with static and dynamic loads. With its interactive nature, the program p...
In forensic science, soil, dust, and vegetable traces have as high a value as evidence as classical traces such as fingerprints or toolmarks. It is imperative that the potential information in these traces can be identified by a combination of analytical methods selected by a qualified expert. Experience has shown that the best results can be expected when all of the aspects of evidence, includ...
fying landscape attributes which are believed to contain similar soils (Hudson, 1992). “Landscape position” can The key Soil Taxonomy is based upon the idea that certain properbe considered to be a geographic approach to classificaties can be used to define populations of soils from the soil continuum. tion, in which combinations of surficial and stratigraphic The soil mapping paradigm is that ...
Though much research has been conducted regarding traction of tires in soft granular terrain, little empirical data exist on the motion of soil particles beneath a tire. A novel experimentation and analysis technique has been developed to enable investigation of terramechanics fundamentals in great detail. This technique, the Shear Interface Imaging Analysis Tool, provides visualization and ana...
Agricultural research has been profited by technical advances such as automation, data mining. Today ,data mining is used in a vast areas and many off-the-shelf data mining system products and domain specific data mining application soft wares are available, but data mining in agricultural soil datasets is a relatively a young research field. The large amounts of data that are nowadays virtuall...
The aim of the study was to investigate the effects of land use on soil quality parameters using multivariate statistical analysis. Soil samples (0-25 and 25-50 cm depths) were taken from three land uses in forest area of Marivan including forest, rangeland, and cultivated land. Soil characteristics of pH, EC, sand, silt, clay and CaCO3 content, water-stable aggregates and their organic carbon ...
Soil quality can be assessed by numerous soil variables (Mausbach and Seybold 1998). In addition to physicochemical variables, biotic variables also refl ect soil quality (Pankhurst et al. 1997). Soil variables often show different patterns of response to the same impact (Jha et al. 1992), refl ecting the multidimensional quality of soil health (van Straalen 2002). These soil variables are asso...
Soil particle size distribution (PSD), one of the most important soil physical attributes, is of great importance to soil water movement, soil erosion and soil solute migration. In this study, the soil PSD of 563 soil samples from the mulched drip irrigated cotton fields in Xinjiang of China were measured by laser diffraction particle size analyzer. The soil PSD characteristics and its relation...
ABSTRACT- The information on the spatial properties of soil is vital to improve soil management and to increase the crop productivity. Geostatistical analysis technique is one of the most important methods for determining the spatial properties of soil. The aim of this study was to investigate spatial variability of soil chemical and physical attributes for field management in eastern Shiraz, I...
