Long and short pile plate structure for controlling differential settlement of highway transition section and construction method of long and short pile-plate structure

The invention discloses a long and short pile plate structure for controlling differential settlement of a highway transition section and a construction method thereof.The long and short pile plate structure comprises a transition section and a common section, reinforced concrete slabs are arranged on the transition section and the common section, and a plurality of prestressed pipe piles are arranged in the transition section and located below the reinforced concrete slabs; a plurality of cement mixing piles are arranged in a common road section below the reinforced concrete slab, the prestressed pipe piles and the cement mixing piles are directly and rigidly connected with the reinforced concrete slab, the lengths of the prestressed pipe piles are gradually decreased in the bridge road direction, and the pile intervals of the cement mixing piles are gradually decreased in the road bridge direction. The long and short pile plate structure and the construction method are good in reinforcing effect, reliable i
