Geosynthetic encased stone columns are often designed using the conventional framework of saturated soils ignoring influence in-situ unsaturated soil conditions. This article evaluates performance with and without geosynthetic encasement extending mechanics ofunsaturated soils. The focus numerical simulations was directed towards understanding matric suction on confining support offered by surr...

Rainfall-induced landslide is a common natural hazard, and one of the disaster-causing factors loss apparent cohesion that mainly caused by dissipation matric suction. To analyze rainfall-induced landslide, especially post-failure behaviors, suction model proposed incorporated into Discontinuous Deformation Analysis (DDA). In this model, simplified as an equivalent line load updated at each tim...

A variety of techniques to measure matric potential or water potential in the laboratory and in the field are described in this section. The techniques described herein require equilibration of some medium whose matric or water potential can be determined from previous calibration or can be measured directly. Under equilibrium conditions the matric or water potential of the medium is equal to t...

To better understand the salinity effect on compaction behaviour of soil, standard Proctor test was conducted soil samples with different salinities. Matric suction and small-strain shear modulus, Gmax, were determined pore size distribution also investigated statically compacted at water contents. Results showed that decrease from initial value 2.1‰ (g salt/kg dry soil) to zero, maximum densit...

This paper presents an interpretation technique to quantify the effects of compaction state and matric suction on undrained shear strength compacted clay under confined triaxial compression. novel is based mathematical frameworks SHANSEP (Stress History Normalized Soil Engineering Property) method for saturated soil BBM (Barcelona Basic model) unsaturated soil.
