Abstract
A poor foundation reinforcement system and a reinforcement method based on underground concealed arch structures are provided. The system and the method belong to the technical field of poor foundation treatment. The reinforcement system includes multiple columns of pile foundations arranged along a bridge direction. Multiple arch sheets are set in parallel between each two adjacent columns of pile foundations. Each arch sheet includes multiple high-pressure rotary jet piles arranged along the bridge. Each two adjacent arch sheets of the multiple arch sheets are connected by a micro-bending slab disposed on the two adjacent arch sheets, the multiple arch sheets are connected by the micro-bending slabs to together form an arch ring, and a construction joint is disposed between each two adjacent micro-bending slabs of the micro-bending slabs.
