Matric suction of compacted soils

, 2016
This project covers the direct and indirect measurement of matric suction of compacted soil. The soil used in this project was Bukit Timah Granite residual soil. Residual soil was compacted with standard Proctor and modified Proctor effort.

Long-term matric suction measurements in highway subgrades [PDF]

, 2006
The performance of Thin Membrane Surface (TMS) highways is largely controlled by the strength of the subgrade soil which in turn is a function of the soil suction (Fredlund and Morgenstern, 1977).

Instrumentation and matric suction measurement in a decomposed granite soil slope

, 2005
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. Matric suction

A Simple Method Using High Matric Suction Calibration Points to Optimize Soil–Water Characteristic Curves Derived from the Centrifuge Method

Agriculture
The centrifuge method serves as an efficient and rapid approach for determining the soil–water characteristic curve (SWCC). However, soil shrinkage during centrifugation remains overlooked and prior modified methods may suffer from complex operations ...

Governing failure mode of unsaturated soil slopes under rainwater infiltration

E3S Web of Conferences, 2016
Due to rainwater infiltration and loss of matric suction above the wetting font, both translational and rotational slips may occur in an unsaturated soil slope. It is useful to know which failure mode is more critical.
