A study of the soil-water reliability model in the whole matric suction range
Shuiwen dizhi gongcheng dizhi, 2022 Soil–water characteristic curves (SWCCs) are considered as a basis for analyzing fluid–solid coupling of unsaturated soil. How to estimate the SWCC over the whole region with matric suction based on the limited local datasets is challenging.

Polymer tensiometers with ceramic cones: direct observations of matric pressures in drying soils [PDF]
, 2010 Measuring soil water potentials is crucial to characterize vadose zone processes. Conventional tensiometers only measure until approximately −0.09 MPa, and indirect methods may suffer from the non-uniqueness in the relationship between matric potential ...

Deformation, strength and water variation characteristics of unsaturated compacted loess
Case Studies in Construction Materials, 2022 The bearing capacity and safety of geotechnical structures are determined by the shear strength of soil. Soil is usually unsaturated in nature, and variation in unsaturated strength is very complicated.

A method for predicting the influence of matric suction changes on CPT tip resistance [PDF]
E3S Web of Conferences, 2019 The Cone Penetration Test (CPT) is a valuable tool for continuous soil profiling and estimating soil properties. A CPT sounding will often pass through the active zone of an unsaturated soil profile, near the ground surface where moisture conditions and ...

An Active Control System for Matric Suction Measurement
Soils and Foundations, 2009 Matric suction is an important stress state parameter in unsaturated soil mechanics. Many studies have been carried out in the past to determine the matric suction through direct and indirect methods. Direct measurement of matric suction has been proven possible with high-suction tensiometer; however high-suction tensiometers are still susceptible to ...
