Deep-Footing and Wide-Slab Effects in Reinforced Sandy Ground

Behaviour of prestressed geotextile-reinforced sand bed supporting a loaded circular footing

“…They clearly show the steady and significant increase in the ultimate bearing capacity when D f /B increases from 0 to 1. The experimental results for reinforced sand foundations are also in very good agreement with theoretical calculations based on modified Huang and Menq (1997) bearing capacity equation, using the friction angle obtained from the plate-load test data.…”

“…The relationship suggested by Huang and Menq (1997) was used to determine the theoretical bearing capacity of reinforced sand.…”

The use of geosynthetics to improve the performance of foundations in civil engineering

“…Huang and Menq (1997) suggested an empirical formula for reinforced soils after the 'deep footing' effect reported by Schlosser et al, where the reinforcement spreads the load with depth, such that the system can be modelled as a wider footing acting at the depth of the last reinforcement layer.

Numerical analysis of shallow foundations on geogrid reinforced soil

“…Since the original work by Binquet and Lee, several laboratory model test studies have been published relating to the improvement of the load-bearing capacity of shallow foundations supported by sand reinforced with various materials such as geogrids [3,4], geotextiles [5], rope fibers [6], metal strips and metal bars [7][8][9][10][11][12].…”
