Abstract Research purposes:The anchor rod retaining wall is widely used in high slope engineering. The research of anchor rod retaining wall limit state design is to examine the safety of the structure in the current design specification, and give design expression to anchorage segment limit state.
Research conclusions:(1) The research steps of anchor rod retaining wall structure 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) For the anchor rod retaining wall structure reliability index, most of recommended values can satisfy the public demand, but when the slope is higher, the reliability index is low. (3) The anchor rod retaining wall can be designed with reference to the current Code for Design of Railway Retaining Structures of Railway Subgrade, when the slope is higher, it is suggested that the partial coefficient of load is appropriately increased, and attention is paid to the design of slope form and slope surface reinforcement. (4) The research conclusion can be used for reference in the design of anchor rod retaining structure.
