Abstract

Diaphragm wall foundation is one-wall type foundation of rectangular section without pile cap, and appropriate for neighboring construction because of littleness of excavation volume. Authors have conducted a series of loading tests using full-scale models (vertical: 2, horizontal: 4) for the purpose of establishing reasonable design method on this new type foundation at the site for Dai-ni Tokai Highway viaducts. This paper describes not only the end bearing capacity and skin friction of this foundation based on the results of vertical loading tests but also the useful information on lateral loading capacity of this method obtained from comparing experimental results with the corresponding simulation analyses.
