Guide to Retaining Wall Design

This Guide to Retaining Wall Design is the first Guide to be produced by the Geotechnical Control Office. It will be found useful to those engaged upon the design and construction of retaining walls and other earth retaining structures in Hong Kong and, to a lesser extent, elsewhere. This Guide should best be read in conjunction with the Geotechnical Manual for Slopes (Geotechnical Control Office, 1979), to which extensive reference is made. The Guide has been modelled largely on the Retaining Wall Design Notes published by the Ministry of Works and Development, New Zealand (1973), and the extensive use of that document is acknowledged. Many parts of that document, however, have been considerably revised and modified to make them more specifically applicable to Hong Kong conditions. In this regard, it should be noted that the emphasis in the Guide is on design methods which are appropriate to the residual soils prevalent in Hong Kong. Many staff members of the Geotechnical Control Office have contributed in some way to the preparation of this Guide, but the main contributions were made by Mr. J.C. Rutledge, Mr. J.C. Shelton, and Mr. G.E. Powell. Responsibility for the statements made in this document, however, lie with the Geotechnical Control Office.
