ABSTRACT
Several different software packages have been used to develop a practical design for the development of a site located on an active landslide overlooking Portland Harbour, on the cost of Dorset, UK. Three new dwellings are proposed which will require extensive foundation engineering works to stabilise the slope, retain the public highway, and support the new development.
This paper considers the implementation of a range of computer-based geotechnical software packages used to model the geotechnical process at play on the site and to design a practical to install foundation solution.
A combination of embedded retaining wall, slope stability, pile design and finite element software was used to examine the stability of the slope, assess the forces on the structural elements and size the foundation works. This required complex soil-structure interaction modelling to size the individual elements and consider the interaction between them.
