Before laying foundation on any type of ground, it is important to determine the expected type and magnitude of settlement in order to ascertain if it is within the set serviceability limit. In this paper, both analytical and numerical analysis of settlement of shallow foundation in sandy ground was carried out with the aim of establishing the relationship between foundation depth and settlement as well as the effect of size of footing to the magnitude of settlement. Schmertmann method (strain influence factor method) which is usually based on Cone Penetration Test (CPT) data was used. On the other hand, FEA analysis was carried out using Plaxis software package. Strip footings (size 10m by 1m and size 20m by 2m) and square footings (size 1m by 1m and size 2m by 2m) were used. The depths used were 0.5m, 1.0m, 1.5m and 2.0m. The footings were subjected to a uniformly distributed loading of 100kPa on sandy soil. The analytical results indicated that an increase in foundation depth leads to a decrease in settlement. It was also noted that foundation width is proportional to settlement. This is as a result of increase in total load carried by the footing. It was also observed that strip foundations experience more settlement than a square foundation of the same width under the same unit pressure. There was a difference between FEA results and the analytical results because of nonhomogeneous, time-dependant and anisotropic nature of natural soil deposits which was not fully taken into account during FEA analysis. The soil body also collapsed during FEA analysis when the bearing capacity was reached hence the full load was not applied. It was recommended that FEA tools should be improved by fully incorporating soil behaviour such as nonlinear, nonhomogeneous, time dependent as well as anisotropic. They should be able to incorporate laboratory and field data from tests such as Standard Penetration Test (SPT), Cone Penetration Test (CPT), Pressuremeter Test (PMT), and Field Load Test among others. Further study using other analytical methods that are based on Standard Penetration Resistance Pressuremeter Test was also recommended. Moreover, further study using other Geotechnical FEA software packages such as FB-MultiPier, Geo FEM, and Z-Soil was recommended.
