Experimental investigation of matric suction in compacted fine-grained soils
International Journal of Pavement Engineering, 2016AbstractThis paper presents the results of laboratory tests performed to study the effect of compaction properties on the development of matric suction in four different soils (three soils were classified as silty clay and one was classified as silty sand). The soils were compacted at the optimum water content (OWC) and wet and dry of optimum according

Influence of Matric Suction on the Stability of Unsaturated Slope
Advanced Materials Research, 2012Matric suction plays a significant role in the unsaturated slope stability and receives a rising interest in how matric suction affects the unsaturated slope stability. According to the shear strength theories and soil-water characteristic curve of unsaturated soils，matric suction parameters were proposed to study the influences of matric suction on ...

Modified Null Pressure Plate Apparatus for Measurement of Matric Suction
Geotechnical Testing Journal, 2010Abstract The null pressure plate apparatus is conventionally used in the measurement of matric suction of fine-grained unsaturated soil specimens applying the axis-translation technique. This apparatus is typically used to measure the matric suction in the range of 50–500 kPa in a laboratory environment.

Principle and Prototype Testing of a New Matric Suction Sensor
Geotechnical Testing Journal, 2010Abstract A new principle for matric suction measurement is proposed, based upon strain measurement of a contiguous porous material of high air-entry value (AEV). In theory, this allows for the measurement of matric suction without the associated errors due to cavitation or hysteresis for suctions below the AEV.

Development of a Soil Matric Suction Direct Measurement Probe
2015This paper presents the development of a soil matric suction direct measurement probe, based on the instrument originally designed at the Imperial College by A. M. Ridley and J.M. Burland. The prototype is capable of measuring suction values up to 1500 kPa with a theoretical resolution of 7.5kPa.

Role of Matric Suction in Collapse of Compacted Clay Soil
Journal of Geotechnical and Geoenvironmental Engineering, 2000This paper examines the influence of variations in matric suction on the collapse behavior of compacted Bangalore clay soil. The ASTM filter paper method measured the matric suctions of the compacted soil specimens. The matric suction of the compacted clay soil specimens ranged between 50 and 8,000 kPa at the as-compacted $S_r$ values of 90 and 35 ...

The relationship between thermal conductivity and matric suction of soils
2021<p>The soil thermal conductivity (&#955;) and matric suction of soil water (h, the negative of matric potential) relationship has been widely used in land surface models for estimating soil temperature and heat flux following the McCumber and Pielke (1981, MP81) &#955;-h model.

The change of matric suction due to heavy vehicle crossing
2014Classical soil mechanics for unsaturated soils mainly deals with quasi static loading conditions because most laboratory tests, such as triaxial tests, are time consuming due to equilibration processes. Under natural conditions, however, cyclic and even dynamic loading of the unsaturated soil may occur with the soil response of suction and saturation ...
