Assessment of Subsurface Competency Using Geotechnical Method of a Proposed Structure F.C.T Nigeria DOI:  https://doi.org/10.30564/agger.v4i4.5133 Received: 11 October 2022 Revised: 24 November 2022 Accepted: 30 November 2022 Published Online: 30 December 2022 Abstract Structural failure has been recently happenings mostly in the commercially populated states along the coastal line in Nigeria. As a result, an open field at a chosen location in Abuja, Nigeria, was investigated. For the purpose of this study, test bores were drilled and Standard Penetration Tests (SPT) were conducted at every 1.5 m interval up to a maximum depth of 12.0 m with the bearing pressure ranging between 20 kN/m2 and 1000 kN/m2 . 3 test bores were drilled within the plot location, and samples were obtained at the test bore’s locations for laboratory analysis. Findings revealed that subsurface lithology found at the site within the explored depths of 0.0-12.0 m is mostly silty sand, laterite, s...

Bioclimatic Regularities of Change in the Density of Organic Carbon of the Steppe Soil in Different Regions of the World DOI:  https://doi.org/10.30564/jasr.v4i1.2521 Abstract The bioclimatic regularities between the average annual precipitation, average annual temperatures and the density of organic carbon in the soil layer of 0-30 cm of the steppes in the regions of the world are given. They are distinguished by a high certainty of quantization by asymmetric wave equations. It turned out that, due to the vibrational adaptation of organic carbon, precipitation and temperature are dependent on each other. For example, the model of the influence of precipitation on temperature includes the first term in the form of Laplace’s law (in mathematics), Mandelbrot’ law (in physics), Zipf-Perl (in biology), and Pareto (in econometrics). The second term is the biotechnical law of the author of the article, which gives the maximum change in the indicator. Both components form a trend that mak...

As a result, an open field at a chosen location in Abuja, Nigeria, was investigated. For the purpose of this study, test bores were drilled and Standard Penetration Tests (SPT) were conducted at every 1.5 m interval up to a maximum depth of 12.0 m with the bearing pressure ranging between 20 kN/m2 and 1000 kN/m2 . 3 test bores’ were drilled within the plot location, and samples were obtained at the test bores locations for laboratory analysis. Findings revealed that subsurface lithology found at the site within the explored depths of 0.0 ~ 12.0 m is mostly silty sand, laterite, sandy clay, silty clay, clayey sand, and weathered rock.
