SUPPORTED EXCAVATION IN WEAK CLAY

The performance of a supported (or braced) excavation is influenced by a large number of variables. These variables, together with the complex interaction and behaviour of the soil and supporting materials, are the subject of the text. The parameters involved in the performance of a braced excavation was acquired by studying the detailed case records obtained during the construction of the Oslo subway. Using this information as a guide a computer program was developed which could adequately model a braced excavation and which incorporated as many of the parameters as possible. The details of the case study and a description of the computer program, together with a user's manual, three example problems and a program listing, are included. /RTAC/
