The net safe bearing capacity ( q ns ) is a significant factor in foundation design. There are several ways published in previous studies to determine the net safe bearing capacity, however choosing the best method governs the stability of the structure when it is loaded beyond its capacity. The emphasis of this concern is investigated and presented in this paper by comparing the net safe bearing capacity of shallow foundations determined by three distinct approaches. Standard Penetration Test (SPT) on cohesion-less soil was carried out in several regions of Vizag to assess penetration resistance of the soil. The findings of this test were subjected to possible corrections, which eliminated the possibility of overestimating the resistance to penetration. Teng’s, Terzaghi’s, and the IS code approach were used to calculate net safe bearing capacity ( q ns ) using these test parameters. According to the final results of this study, the net safe bearing capacity of Terzaghi’s and IS code methods were 1.2 times and 2 times higher than the Teng’s method. As a result, the IS code method overstated the net safe bearing capacity by two folds, which may potentially cause the structure to fail and increase the structure’s economy. As a result of these findings, Teng’s method was reported to be the best approach for determining the net safe bearing capacity of cohesion-less soils.Read More
