Effect of Overload on Bearing Capacity of FRP Reinforced Ground

Abstract:

Concrete blocks were arranged on both sides of the strip foundation to simulate overload. Model tests with overload or not were conducted, for four test programs including pure sand ground, single plate reinforced ground, double plates reinforced ground and single plate with two anchorage ends reinforced ground. The influence of overload on bearing capacity and settlement of ground, earth pressure and strain of FRP was analyzed. The test results showed that overload can enhance the bearing capacity, and reduce the ground settlement in a certain extent, with the beneficial effects of overload on reinforcement effect being decreased while the amount of reinforcement was increased.
