A series of laboratory model loading tests were performed on strip foundations supported on unreinforced and geotextile-reinforced transparent soils. Fused silica sand and white oil were carefully mixed to prepare the transparent soil. The transparent soils were reinforced with geotextiles with the spacing of 0.25B and 0.5B, the length of 1B to 7B, and the depth of 0.5B, 1B and 1.5B (B is the width of the foundation). The deformations of the soils and geotextiles were monitored using a digital camera and a laser transmitter. The results show that for the soils with reinforcements of 0.5B spacing, the deformations of the geotextiles show that each peak point observed in the curves of the bearing capacity improvement versus foundation settlement is related to the failure of one layer of reinforcement, which indicates the progressive failure of different layers of reinforcements. However, for the soils with reinforcement of 0.25B spacing, failure of layers of reinforcements occurs from bottom to top. Moreover, most of the foundations show brittle failure behavior. It also reveals that the bearing capacity of reinforced soil foundation does not always increase with the increase in length of reinforcements when suitable reinforcement spacing is chosen.
