NettetSand boils, a common indication of soil liquefaction, are more frequently observed in the lower portions of a lateral spread. Lateral spreading is defined here to include only lateral sliding of gently sloping ground due to soil liquefaction at relatively shallow depths, and does not refer to the large horizontal NettetThe coefficient of linear extensibility (COLE) measures soil swelling of natural soil clods and was designed for use in soil genesis and characterization studies. In an attempt to quantify engineering ratings of shrink-swell potential and to enhance nonagricultural use of soil survey data COLE has been statistically related to arbitrary PVC values.

"Nettet14. mar. 2024 · Linear extensibility is used to determine the shrink-swell potential of soils. It is an expression of the volume change between the water content of the clod at 1/3- or 1/10-bar tension (33kPa or 10kPa tension) and oven dryness. Volume change is influenced by the amount and type of clay minerals in the soil. The volume change is … " - Linear extensibility of soils

Abstract- The study investigated geotechnical properties of soils along with other soil’s properties and classified soils derived from Imo Clay Shale. NettetThe coefficient of linear extensibility (COLE) is a quantitative expression of the capacity of a soil to swell when moist and to shrink and crack when dry. COLE values are used to characterize soils in their natural condition and to group them according to their swelling tendencies. They are useful in predicting potential swelling problems with agricultural …

Due to the physical and chemical properties of some clays (such as the Lias Group) large swelling occurs when water is absorbed. Conversely when the water dries up these clays contract (shrink). The presence of these clay minerals is what allows soils to have the capacity to shrink and swell. Some of these clay minerals are: smectite, nontronite, bentonite, chlorite, montmorillonite, beidellite,
