According to model tests of pure sand foundation

horizontal reinforcement foundation and horizontal-vertical (H-V) reinforcements foundation

the influences of single layer H-V reinforced depth and number of H-V reinforced layers on foundations are studied. Through comparing the horizontal reinforcement foundations and combining the sliding surface of H-V reinforced soil

the reinforcement mechanism is analyzed. The test results show that the reinforced effect of H-V reinforcements is better than that of horizontal reinforcement at the same experiment condition; the bearing capacity decreases with the increase of the single layer H-V reinforced depth; effect of reinforcement on foundation bearing capacity is not obvious when the reinforced depth exceeding a certain range. For multilayer H-V reinforced foundation

bearing capacity increases and settlement decreases with the increase of number of reinforced layers.
