Frequent problems in soil mechanics and foundation techniques - analysis and remedial suggestions
D.G. Goossens

Soil mechanics and foundation engineering have always been something special in the construction process of a project. Boundary conditions are indeed very different from the conditions for other sectors such as stability design or execution of a structure. The design and the execution of an important construction and its foundation are a complex business. Every foundation is a new product that has to be created under always-different circumstances: soil conditions, hydraulic conditions, structures on and next to the foundation, project team, techniques, completion time, budget. There are a considerable number of risks, which can lead to damage. A lot of research about foundation defects has been done. Case histories of failures should be recognized and exploited as major sources of insight and judgement in design and construction. A broad approach of the project can lead to damage limitation, to quality improvement and to rationalization. This approach can be multiple: technical analysis of the whole (foundation and structure, soil investigation, existing structures, boundary conditions), risk management by an overall approach on the one hand and by considering adjusted measures on the other (quality control, latent defects insurance).
