ABSTRACT
There are many different types of earth retaining structure. The rst stage in the design process is therefore to assess the appropriateness of the available types of structure for the given application. Following this, the possible ways in which a given structure might fail to perform satisfactorily should be considered (see Chapter 7). Preliminary design may then be carried out on a number of different types of retaining structure, to assess their viability, and nally detailed design calculations will be undertaken. During the selection of appropriate types of retaining structure, it will be necessary to have an approximate idea of the types of subsoil and their distribution around the proposed wall location.
