Original vertical joints (OVJs), which are highly correlated with loess anisotropy, have been
considered a non-tectonic source of extensive erosion, gully development, and landform …

Polymer-modified bentonite has been widely used in vertical cutoff walls due to its good
barrier properties. This paper illustrates the changes in fissure development and …

Densely compacted loess on which many man-made infrastructures are built are often
exposed to strong weathering processes such as repeated wetting-drying (WD) and freeze …

Soil–bentonite slurry-trench cutoff walls using backfill consisting of on-site sandy soil and Na-
bentonite are extensively used as engineering barriers for the purpose of achieving …

This paper investigates the volumetric, microstructural, and shear behaviours of an
expansive soil during multiple drying-wetting (DW), freeze–thaw (FT), and drying-wetting …

This study aims to investigate workability and microstructural characteristics of sodium
hexametaphosphate (SHMP)-treated calcium bentonite (Ca-bentonite) as a potential …

The performance of clay liners may be impaired when in contact with aggressive solutions
due to cation exchange. The efficiency of these liners can further deteriorate if cation …

Hydraulic conductivity of polyanionic cellulose (PAC)–amended bentonite (PB) in calcium
chloride (CaCl 2) solutions was investigated to access its chemical compatibility in vertical …

Compacted loess is widely used as fills of road embankments in loess regions of northern
China. Generally, densely-compacted loess can satisfy the requirements of embankment …

Rainfall infiltration softens the filling material of deep cracks in expansive soil, significantly
reducing its mechanical strength and causing slope instability and failure. Investigating this …
