“…In northern Jordan, the location of the plant fossil locality, the thickness of the underlying Jurassic sediments is variable (Basha 1983). Conformably overlying the Kurnub Group is the Cenomanian Nodular Limestone Member of the Na'ur Formation, Ajlun Group, and the change in facies is assumed to be between the Albian and Cenomanian stages (Al-Homoud et al 1996).…”

“…The influence of water on the expansive soil slopes can be analyzed by several aspects: firstly, the increase of water content will change the physical and mechanical properties of expansive soil significantly, mainly causing an increase in porosity, a decrease of intergranular coupling force, etc. Meanwhile, a large number of desiccation cracks occur in the shallow layer of the expansive soil slopes under the action of the atmospheric dry-wet cycle, and the cracks cause a large amount of rainwater infiltration, which results in a decrease or even loss of the matric suction, eventually leading to a decrease in the shear strength [4,[15][16][17]. Moreover, some scholars have proposed that the influence of the current static and dynamic load on the slope stability should also be considered from the perspective of seepage force during rainfall infiltration [14,[18][19][20].…”

A large number of instability cases and laboratory tests of expansive soil slopes show that its shallow layer destruction happens because of the insufficient shear strength under the usual action of low stress and repeated dry-wet cycles. We can obtain the strength nonlinear distribution law fitted by generalized power function based on a series of shear strength tests of expansive soil considering low stress and can construct the numerical model considering the nonlinear strength distribution by FISH, to realize the shear strength dynamic distribution with the vertical stress. Based on the numerical model, the whole-process contrastive analysis has been conducted on the stress field, the slip surface depth, and the seepage field of plain soil and reinforced expansive soil cut slope under different rainfall conditions. Besides, the mechanics characteristic of the geogrid under various design schemes has been compared and analyzed. A further explanation has been given for the expansive soil cut slope prone to shallow layer failure after rainfall and on the effect of geogrid reinforcement. The numerical results provide a reference for slope stability analysis in rainy expansive soil areas.

“…While Ohtsubo et al [6] examined the correlation of clay mineral composition with the consistency limits and activity of the clays for marine clays from Singapore, Korea, and Japan. Al-Homoud et al [7] evaluated the chemical and engineering properties of the clayey beds in some locations in Jordan and correlated the clay minerals associated with the clayey beds with their engineering properties. The main property that distinguishes the clay is its plasticity therefore; several attempts have been made to achieve a numerical index to emphasize the relationship between mineralogy and plasticity.…”

The demand of clay as a raw material for many industries has increased in recent years due to their physical-chemical and plastic properties. The main property that distinguish the clay is its plasticity therefore; several attempts have been made to achieve a numerical index to emphasize the relationship between mineralogy and plasticity. (EBS) Equivalent Basal Spacing maybe is the most recent contribution for this purpose. In this paper, we analyze different types of Syrian clay samples, from five locations, by measuring their Atterberg limits and their mineralogical composition, in order to check the validity of the EBS method. As consequence, we find a positive connection between Atterberg limits and the relative amount of phyllosilicates present in samples. The EBS factor provides a good relationship between mineralogy and plasticity of the samples, by giving an easy and reliable correlation based on the direct determination of the liquid limit and plasticity index based on the mineralogical composition of the studied clays. We recommend for further researches to study the relations between EBS and Atterberg limits for other types of clay around Syria in order to validate EBS parameters in most applications. .
