The previous thesis (Part 1) presented a two-dimensional calculation method for a cylindrical earth retaining structure subjected to wall temperature variations, in addition to lateral pressures. In this study, the authors work out numerical analysis of mechanical behavior of a cylindrical RC earth retaining structure (144m in diameter and 30m in excavation depth). Especially, they take into account (a) the rigidity of the composite wall (earth retaining wall with RC basement wall), and (b) non-linear distribution of wall temperature variations in the composite wall. They compared the results with experimental data, and proved that the cross-sectional stress distribution of reinforcing bars in the composite wall is discontinuous across the interface of the earth retaining wall to the basement wall.
