In the last decades, several engineering works have been developed in Northeast of Brazil, a region marked by occurrence collapsible and expansive soils. This work aimed to characterize study behavior two samples residual soils collected municipality Salgueiro-PE regarding their collapse potentials shear strength parameters, natural disturbed conditions, evaluating influence applied vertical st...

considerable information exists in the literature showing that expansive layer silicates are not the only clay minerals present in vertisols. however, the presence of a very high clay content dominated by fine clay, regardless of the clay type, together with the wetting and drying cycle in the soil can also produce a high shrink-swell potential. we studied some vertisols with diverse parent mat...

This research developed a numerical-hierarchical framework that captured surface conditions and climate parameters. Volume changes under distinct scenarios of boundary, antecedent moisture, meteorological parameters were predicted using coupled seepage-deformation model. Risk was hierarchically based on expert judgment for (Stage-I indices) normal distribution moisture atmospheric (Stage-II ind...

Expansive soils increase their volume upon wetting, but under high vertical stresses may exhibit collapse, with the latter aspect being rather overlooked in foundation engineering. Oedometer swelling/collapse tests on expansive Pliocene marls of various calcium carbonate content and plasticity index sampled from Nicosia, Cyprus, indicate that, unlike free swelling strain, pressure is insensitiv...

Let $ H$ be a Hilbert space and $C$ be a closed, convex and nonempty subset of $H$. Let $T:C rightarrow H$ be a non-self and non-expansive mapping. V. Colao and G. Marino with particular choice of the sequence  ${alpha_{n}}$ in Krasonselskii-Mann algorithm, ${x}_{n+1}={alpha}_{n}{x}_{n}+(1-{alpha}_{n})T({x}_{n}),$ proved both weak and strong converging results. In this paper, we generalize thei...
