ABSTRACT
The behaviour of foundations on clay soil reinforced with geo-textile using laboratory model footing tests was investigated. The square model footing was made of a steel plate with dimensions of 150 mm × 150 mm. The parameters investigated in this study included the top layer spacing, the length of reinforcement layers, and the type of geotextile. The test results showed that the inclusion of reinforcement could significantly improve the soil’s bearing capacity and reduce the footing settlement. The increase in BCR values varied depending on the type of geo-textile and how it dealt with the soil. BCR increases as u/B in-creases until it reaches a certain point where it decreases. The maximum improvement is achieved at u/B=0.3 for both types, this value varying depending on the length of the geotextile. The values of L/B that achieve a higher BCR are 3 and 8 for woven and nonwoven, respectively. The results show that woven geotextile has superior BCR values; how-ever, in practice, nonwoven can achieve excellent performance with less reinforcement than woven.
