Abstract：Research purposes:The pile plate retaining wall is a common retaining structure. The research on pile plate retaining wall limit state design is to examine the safety of the structure designed according to the current design specification, and give design expression of anchorage segment limit state. This paper has summed up the research thought of pile plate retaining wall and analyzed the main calculation results, which provides a reference for pile plate retaining wall limit state design. Research conclusions:(1) The research steps of the pile plate retaining wall limit state design are to establish a limit state equation, calculate reliability index and determine the target reliability index, calculate partial coefficient and set up the design expression. (2) The reliability index analysis of shoulder type pile plate retaining wall showed that the reliability index meet or close to the demand of the public. (3) The pile plate retaining wall can be designed with reference to the current code for design of railway retaining structures of railway subgrade, but for the design of the high slope embankment and cutting wall, the partial coefficient of larger loads should be adopted, at the same time in the design attention should be paid to the measures to reduce the earth pressure of slope. (4) The design expression for calculating the shoulder type pile plate retaining wall anchoring segment and recommended values of partial coefficient are proposed. (5) The research conclusion can be used for reference in design of the shoulder type pile plate retaining wall.
