Abstract: Volume change in argillaceous sediments can take place due to either swelling of expansive clay or gypsification of anhydrous calcium sulfate. Gypsification offers a variety of serious geotechnical hazards such as high ...

Abstract: Recent work conducted on a salt‐encrusted, surficial soil, known as sabkha, indicated that the conventional oedometer apparatus was incapable of detecting the collapse potential. This study proposes a modification to the ...

Abstract: Arid climate, alkaline environment, and geology govern the formation and behavior of coastal calcareous sediments in the Arabian Gulf region. The presence of clay and nonclay minerals in these sediments causes geotechnical ...

Abstract: This investigation is carried out: (1) To study the effect of magnesium‐sodium sulfate environment on the performance of two plain and three blended cements; and (2) to elucidate the sulfate attack mechanisms on these ...

Abstract: Along the western shores of the Arabian Gulf, saline soils, known as sebkhas, are widely distributed. These soils are associated with many geotechnical problems that emerge principally because of their high salt content ...

Abstract: This paper presents a modification to the classical cap model by including the third stress invariant and the kinematic hardening rule in the formulation. An isotropic‐kinematic hardening rule for cohesionless soils is ...

Abstract: A method of calculating soil cover requirements for horizontally bent buried pipelines is described. In sequence, the results of a comprehensive three-dimensional finite element analysis are used ...

Abstract: This paper discusses the stability of underground pipelines with preformed vertical bends buried in sandy soil. More specifically, the minimum cover height required to prevent the pipe from ...
