Improvement of Bearing Capacity of Shallow Foundation on Geogrid Reinforced Silty Clay and Sand

Table 7

Comparison of ultimate bearing capacity based on 𝑢/𝐵 ratio.

No. of geogrids	Test types	𝑢/𝐵	UBC (kN/m^2)		% improvement
			10% BM	TIM	10% BM	TIM
1	1 geogrid in the interface of silty clay soil and sand layer	0.67	248.98	153.22	N/A	N/A
1	1 geogrid at the sand in two-layer condition	0.33	229.83	172.37	14.28	12.50
