Abstract
This paper presents an easy-to-use two-dimensional calculation method for a cylindrical-shape cantilever earth retaining structure, as affected by the three external factors, they are: the lateral pressures, mean wall temperatures, and differential temperatures. In this method, the results are obtained by superposing the individual solutions due to the three external factors, as above. Correction for their mutual interaction is then introduced in terms of the subgrade reaction of soil. The authors compare behaviors of the said retaining structure calculated (a) by the two-dimensional calculation method, and (b) by the conventional three-dimensional FEM analysis. Their satisfactory agreement proves usefulness of the present two-dimensional calculation method.
