The invention discloses a bridge tower supporting structure suitable for a deepwater area and a construction method, and belongs to the field of bridge engineering. The bridge tower supporting structure sequentially comprises a plurality of steel pipe piles, a cushion layer, two prefabricated caissons and two reinforced concrete stand columns from bottom to top. The multiple steel pipe piles are arranged at intervals and used for being inserted into a soft soil layer below a foundation pit. The cushion layer is used for being laid at the bottom of the foundation pit, and the top ends of the steel pipe piles are inserted into the cushion layer. The prefabricated caissons are located on the cushion layer, skirt tubes are arranged at the bottoms of the prefabricated caissons and penetrate through the cushion layer, and the tops of the steel pipe piles are located in the corresponding skirt tubes. Each reinforced concrete stand column is composed of an outer steel cylinder, an inner steel cylinder and concrete po
