Abstract Recently, microbial biopolymer-based soil treatment (BPST) has gained attention for its application in environmentally friendly stabilization, particularly enhancing the strength and stability of fine-grained soils. However, effects BPST on clay’s compressibility (consolidation) expansion (swelling) behaviors remain unclear. This study used xanthan gum, a microbially produced polysacch...

The stability of unsupported rectangular excavations in undrained clay is examined under the influence anisotropy and heterogeneity using three-dimensional finite element upper lower bound limit analysis with Anisotropic Undrained Shear (AUS) failure criterion. Three anisotropic shear strengths are considered study, namely triaxial compression, extension, direct simple shear. Special considerat...

Recent investigations on tsunami generation from submarine mass failures show that one of the most important factors influencing the source characteristics of the wave is the initial acceleration of the failure itself. In a number of these studies, a translational slide is modeled as a rigid body sliding down an inclined plane and basal resistance is neglected. In this paper, a similar rigid bo...

Fine-grained marine sediments often contain gas bubbles that can cause many geotechnical problems. This soil has a composite structure with fitting within the saturated matrix. The cavity detrimental effect on stiffness and strength when they are filled undissolved only. be pore water due to “bubble flooding”. Bubble flooding beneficial undrained shear because it makes matrix partially drained ...

Construction of civil engineering structures on weak soil without taking necessary precautions may be risky. Alluvial that has not completed its geological formation a high void ratio and contains organic material therefore, the strength properties these soils should examined carefully. In this study, undrained shear (cu) behavior natural polypropylene (PP) fiber-reinforced alluvial clays was i...
