Current limitations and future research needs for predicting soil precompression stress: A synthesis of available data

Soil and Tillage Research
Precompression stress, compression index, and swelling index are used for characterizing the compressive behavior of soils, and are essential soil properties for establishing decision support tools to reduce the risk of soil compaction. Because measurements are time-consuming, soil compressive properties are often derived through pedotransfer functions.

Calculation of the compression index and precompression stress from soil compression test data

Soil and Tillage Research, 2005
Abstract When compressing soil, there is a characteristic relationship between compressive stress and volume change that can be used to define important soil mechanical properties. Two defining features can be determined – the compression index (Cc – the modulus of the slope of the linear virgin compression curve) and the precompression stress (

Determination of precompression stress of an Andisol (Duric Hapludand) using two graphic methods.

, 2009
  En el sur de Chile se ha utilizado ampliamente el método gráfico de Casagrande (1936) para determinar la capacidad de soporte del suelo, sin evaluar si el método es mejor que otros como el propuesto por Pacheco Silva (1970) que se caracteriza por ser de fácil determinación, objetivo y más apropiado para suelos con alta capacidad de deformación ...

CA–MQL grinding of zirconia engineering ceramics under precompressive stress

The International Journal of Advanced Manufacturing Technology, 2022
Abstract Engineering ceramics are widely used in aerospace, 3C electronics, life sciences and other fields. However, the hard brittleness of engineering ceramics makes it difficult to process, prone to damage during processing, and difficult to balance processing efficiency and quality.

Soil Structure under Forest and Pasture Land-Uses Affecting Compressive Behavior and Air Permeability in a Subtropical Soil

Soil Systems, 2022
Machinery traffic and animal trampling can deform the soil and, consequently, impair soil pore functioning. This study aimed to evaluate how soil structure affects the compressibility, physical properties and air permeability of a Typic Paleudalf under ...

Compressibility of a Cambisol Submitted to Periods of Rotational Grazing and Strategies to Avoid Additional Soil Compaction

Conservation, 2023
Soil compaction is one of the main causes of soil degradation, and some parameters have been used to characterize it, like those related to compressibility and the degree of compactness.
