Soft soil area highway foundation reinforcing structure and construction method and supervision method thereof

The invention relates to a soft soil area highway foundation reinforcing structure and a construction method and a supervision method thereof. The soft soil area highway foundation reinforcing structure comprises an asphalt layer, a soft soil layer and a hard soil layer which are sequentially arranged from top to bottom, a plurality of reinforcing piers are buried in the soft soil layer in the length direction of a highway, and the length direction of the reinforcing pier is identical to the width direction of the highway; a plurality of reinforcing steel plates are fixedly arranged between every two adjacent reinforcing piers, the two ends of each reinforcing steel plate are bent downwards, a plurality of reinforcing columns are fixedly arranged at the bottoms of the reinforcing piers, and the bottoms of the reinforcing columns are inserted into the hard soil layer. The reinforcing structure has the effects that large-area excavation of soft soil is avoided, the supporting strength and stability of the roadb
