MEASUREMENTS OF SUCTION AND WATER CONTENT DURING SATURATION OF COMPACTED EXPANSIVE SOIL

Diyala Journal of Engineering Sciences, 2015
The change of climate gives fluctuation of water content in its result rain, evaporation, rising water ground level and evapotranspiration. The expansive soil will volume change and suction. This behavior can damage on construction structures especially,

Matric suctions to which soils in South Central England drain

, 1972
In a survey of soils in South Central England matric suctions were measured frequently during 1962 and 1963. Results for the period October to May are given for sites lying above the influence of the regional ground water table and show the matric ...

New setup for filter paper matric suction measurement of low permeable powder clay

, 2021
Different measurement techniques have been developed for matric suction measurements, such as tensiometer, axis translation, and filter paper. Among these, the filter paper method is low-cost and measures a wide range of suction. However, it is difficult

Instrumentation and matric soil suction measurement in a decomposed granite soil slope

A field instrumentation program was carried out to measure the matric suction in a granite residual soil slope. The variation in matric suction due to changes in climatic condition was investigated to study its effect on slope stability.

Effect of strength - Matric suction variations on stability of a natural slope

, 1998
Stability analysis of residual soil slopes are now increasingly being performed with the incorporation of the matric suction component of strength. The matric suction (u(a)-u(w)) component of shear strength is known as apparent cohesion.
