Abstract: In order to study the influence of lateral prestressed force and upload on the distribution of earth pressure on the anchor-plate retaining wall and anchor plate and shear stress of wall, a serial of retaining wall model tests and numerical simulation were put forth. The influence law of the different loads to the mechanical features of anchor-plate retaining wall was found. Results showed that, under prestressed force action, the distribution curve of lateral soil pressure of retaining wall was like a parabolic with the peak value around anchored bar. Earth pressure before anchor plate was a saddle distribution along the width of plate with the expanding degree, 35°. In addition, along the axis of prestressed cable, the influence area of earth pressure of anchor plate was about double width of anchor plate. Under upload action, the distribution curve of lateral earth pressure of retaining wall was like an alphabet S curve. There was a big shear stress area near the rooting of retaining wall, where should be strengthened by increasing ratio of reinforcement. Conclusion of this study could provide reference for the population and application of prestressed anchor plate retaining wall in highway engineering.

Key words: anchor plate retaining wall, structure shear stress, upload, anchor plate, earth pressure distribution, prestressed force
