Eff ects of aff orestation on soil structure formation in two climatic regions of the Czech Republic
water-stable aggregates (WSA) mean weighted diameter
2015/5/18
The aim of this study was to determine the effect of agricultural land afforestation on soil characteristics.
Two sites in two regions of the Czech Republic were evaluated, at lower as well as highe...
Probabilistic Analysis of Offshore Wind Turbine Soil-Structure Interaction
Offshore Wind Turbine Soil-Structure Interaction
2014/10/22
A literature review of current design and analysis methods for offshore wind turbine (OWT) foundations is presented, focusing primarily on the monopile foundation. Laterally loaded monopile foundation...

International Workshop on “Soil Structure and its Functions on Ecosystem”-1st an
International Workshop Soil Structure Functions on Ecosystem
2012/12/27
Soil structure is a fundamental property of soil fertility, its ability to transport water, nutrients and gas, and to provide habitat for microorganisms and fauna. Aggregated soil structure can improv...
Non-Linear Seismic Soil-Structure Interaction Analysis Based on the Substructure Method in the Time Domain
Seismic soil-structure interaction substructure formulation finite element method
2009/10/13
This paper presents an idealized 2-dimensional plain strain nite element seismic soil-structure interaction (SSI) analysis based on a substructure method by using original software developed by the a...
Soil-Structure Interaction for a Wedge-Shaped Structure Supported by a Flexible Embedded Foundation for Incident SH Waves
SH waves Dynamic soil-structure interaction Wave passage e ects Dynamic interaction
2009/10/10
A simple model of a wedge-shaped structure supported by a flexible foundation, embedded in an elastic half-space and excited by incident plane SH waves, is considered. For this model, a closed-form so...
An Efficient Seismic Analysis Procedure for Torsionally Coupled Multistory Buildings Including Soil-Structure Interaction
Torsionally coupled multistory buildings Soil-structure interaction Frequency domain analysis
2009/10/10
In this paper, a simpli ed methodology of analysis for the seismic response of 3-dimensional irregular high-rise buildings on a rigid footing resting on the surface of a linear elastic half-space is f...
Intersecting-surfaces approach to soil structure
surface- and volume-like objects pores grains aggregates
2008/11/26
The large number of intersecting surfaces in a volume divides the latter into small sub-volumes. Each of the sub-volumes is outlined or nearly outlined by parts of the intersecting surfaces. A number ...
Advantages of application of the backscattered electron scanning image in the determination of soil structure and soil constituents
backscattered electron scanning image soil structure soil components
2008/11/26
Submicroscopic techniques can be broadly subdivided into the study of micromorphology and imaging of the arrangement of the soil particles and voids, and the microchemical analysis of soil components....
Accessibility of most frequently used physical parameters of soil structure, reliability of measured values, lack of replicates andways out of this dilemma
bulk density saturated hydraulic conductivity limited data-sets outflanking techniques
2008/11/26
Assessment of soil structure and still more its changes is impeded by peculiarities of sampling and measurement. Unavoidable local destructions tend to advance use of small numbers of replicates, samp...
Impact of the long-term straw supply on loess-derived soil structure
plant residues slaking soil structural properties organic matter
2008/11/26
Keeping plant residues on the field and incorporating them instead of removing or burning them, is a well-known practice in soil and water conservation. One of the objectives of this management is to...
Impacts of soil structure on crop growth
soil structure parameters simulation modelling root distribution crop growth
2008/11/24
Intensive agricultural utilisation of soils may change the structural status and through it the credibility and fertility of soils. Since soil structure has not been quantified explicitly, studying st...
Scale cutoffs and the limits of fractal soil structure
fractals soil structure bulk density porosity soil organic matter
2008/11/13
with a scaling factor ranging between b=1.66 and b=6.41. Both the maximum number of model iterations, imax, and n correlated positively with soil organic carbon. Knowing the limits of fractal behavio...
Relations between soil structure, number of selected groups of soil microorganisms, organic matter content and cultivation
soil structure microorganisms organic matter cultivation system
2008/11/12
The aim of this work was to fiut relations between the number of selected groups of soil microorganisms, water stability of soil aggregates, soil porosity and the organic matter content on the basis o...
Seasonal variation of some soil structure indicators
polysaccharides aggregation soil structure
2008/11/12
Seasonal changes of soil carbohydrate and root weight were studied for the grey forest soil at different phases of the growth of barley. The soil structure was characterized simultaneously by soil ag...
