Regarding the complicated factors affecting the force of T-type underground continuous wall structure，this paper analyzes the wharf structure by using the vertical elastic foundation beam method and STAAD software combined with engineering examples，and investigates the influence of different model unit division accuracy，depth of the ground wall and m value of the backfill on the structure of the T-type underground continuous wall.The results show that with the improvement of model element division accuracy，the bending moment of the underground continuous wall increases at sea side，decreases at land side，and the bending moment of the anchor wall structure changes in a contrary way.Finally，the internal forces of both structures tend to be stable.Under the premise of overturning stability，the sea side bending moment of the underground continuous wall decreases，the land side bending moment increases，and the displacement decreases as the depth of the bottom of the wall increases.With the increase of m value，the bending moment on the sea side of the anchor wall increases，decreases at land side，and the sensitivity is higher.The research conclusions can provide references for the design of wharf structure using T-type underground continuous wall.
