AbstractMuch undeveloped, low cost land is underlain by recent deposits on which development is inhibited by high foundation costs. A typical example is an industrial estate at Newport, Gwent, which is underlain to a depth of 8m by alluvium (clays, silts and peat) overlying Glacial Till and Mercia Mudstone. The superficial deposits are relatively soft and foundations are normally piled, thus increasing the overall cost of each structure by about £60/m2. Grid reinforced soil-foundations, in which trenches are backfilled with compacted clay or granular fill reinforced with layers of plastic coated welded wire mesh, were proposed as a possible cheaper alternative. Full scale instrumented trials have been undertaken at the Newport site to assess the viability of such foundations. The grid reinforced clay foundation which was loaded over a 5 year period proved unsuitable but information relevant to embankments was obtained. On the other hand granular soil foundations have shown considerable promise. Under a loading of approximately 300 kPa, the unreinforced foundation failed but the reinforced one was still serviceable. Thus the system was capable of achieving an allowable bearing pressure of at least 100 kPa and appears a viable and economic method of founding on sites underlain by soft Quaternary deposits.

This study investigated the soil bearing capacity and foundation settlement characteristics of Minna City Centre development site using standard penetration test (SPT) data obtained from10 SPT boreholes at 0.6, 2.1 and 3.6 m depths to correlate soil properties. Evaluation of foundation bearing capacity and settlement characteristics for geotechnical preliminary design of foundations was carried out using some conventional empirical/analytical models and numerical modelling. The aim was to investigate and determine the geotechnical parameters required for adequate design of Physical structures of the proposed Minna City Centre, at Minna the capital of Niger state. The SPT N-values were corrected to the standard average energy of 60% (N60) before the soil properties were evaluated. Using the corrected N-values, allowable bearing pressure and elastic settlement of shallow foundations were predicted at 50 kN/m2 applied foundation pressure. The numerical analysis results using Plaxis 2D, a finite element code, shows the analytical/empirical methods of estimating the allowable bearing pressure and settlements of shallow foundations that provided acceptable results. Results obtained show that an average bearing capacity value of 100 – 250 kN/m2 can be used for shallow foundations with embedment of 0.6 to 3.6 m on the site.  http://dx.doi.org/10.4314/njt.v36i3.1

Strength characteristics of foundation soils in the Permanent site of the Federal University Lokoja in Kogi State were evaluated based on standard penetration test (SPT) results using some conventional analytical models proposed by different researchers. The study was carried out in order to take precise engineering decisions on the type of foundations suitable for the proposed structures and to determine the optimal depth of foundation embedment.  The SPT N-values were first corrected to the standard average energy of 60% (N60) before they were used to correlate soil properties. Evaluation of the soil properties were done at foundation embedment depths of 0.6, 2.1 and 3.6 m. Results show that bearing capacity generally increased with boring depth. Based on the Meyerhof allowable bearing pressure estimation method, foundation pressures in the range of 150 – 600  kN/m2 were evaluated for use in the study area at shallow depths (depths in the range of 0.6 - 3.6 m).http://dx.doi.org/10.4314/njt.v36i3.2
