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 …

In the northwest of China, many loess landslides have occurred without clear triggering
factors (ie, rainfall, earthquake, human activities, etc.). To better understand and analyze the …

The mechanical behavior of unsaturated soils can be interpreted using either modified total
stress or a modified effective stress approach depending on the type of soils and various …

Assessing the effect of heavy precipitations on earthen structures warrants studying earth
pressure profiles in unsaturated soils under transient flow. This paper presents an analytical …

An essential hypothesis is that the flow failure landslides occurring in the Chinese Loess
Plateau may initiate in the high-moisture-content loess in the capillary zone rather than in …

Suction-stress characteristic curve (SSCC) is an important constitutive relation defining
variation of effective stress because of changes in soil water content. It can be intrinsically …

The soil water retention curve (SWRC) describes a soil's constitutive relation between matric
suction and volumetric water content. The suction stress characteristic curve (SSCC) …

In this study, an analytical model is developed to establish a framework for predicting the
coefficient of lateral soil pressure in unsaturated soils. To this end, the disturbed state …

To better understand and analyze the unsaturated stability of loess filling body, it is
necessary to study the changes in suction stress before and after the drying-wetting cycles …

Shear strength equation is a basic theory for solving many geotechnical engineering
problems. Although the shear strength equation has received widespread attention, shear …
