Abstract
With the rapid development of road network, it is inevitable that new tunnels will be constructed under existing highway or railway bridges. Open excavation method is a typical way for building a new tunnel under bridge, leading to significant influences of the existing pile friction. Accounting for these issues, pile side grouting reinforcement method has been widely employed to improve the load bearing capacity of existing piles. However, the mechanism of this method is still not clear. In this paper, the compressive load capacity of pile with side grouting reinforcement is investigated. The research results reflect the effect and mechanism of pile side reinforcement on the enhancement of pile friction. For the existing pile in this paper, the reinforcement width has a reasonable range. The compressive load bearing capacity of the pile cannot be improved indefinitely with the increasing of the reinforcement width. Pile with a reinforcement width within 1000 mm shows similar characteristics of enlarged diameter pile. Although ultimate compressive load bearing capacity of these piles is greatly improved, they need a larger displacement to exert load bearing capacity. Shear strength and friction characteristics of the contact surface between the reinforced zone and the pile and supporting capacity of the soil under reinforced zone are the keys to enhance the pile compressive load bearing capacity.
