Abstract: Fiber reinforced polymer (FRP) has good performance such as corrosive resistance, water resistance, high temperature resistance, high strength, high elastic modulus, light weight and so on. FRP materials can be used to enhance reinforcement effects significantly and improve durability of traditional reinforcements. A series of tests was conducted on pure sand and five types of horizontal reinforcement. Settlement, FRP strain and earth pressure were measured under different load levels, and the mechanism of FRP reinforcement was discussed. The testing results show that reinforcement can significantly improve the bearing capacity of the ground and reduce the settlement of foundation. In particular, the effect of double-layered horizontal reinforcement is pronounced, while the influence of anchor installation on the reinforcement is insignificant, and the horizontal FRP reinforcement mainly contributes to distributing the earth pressure.

Key words: strip foundation, horizontal FRP reinforcement, bearing capacity, settlement
