Abstract

Statistics, reliability analyses and risk estimates can be very useful decision-making tools in geotechnical problems. Yet the methods are little used in practice. The offshore and mining industry are at the forefront for the use of these approaches, having encouraged their use and sponsored research that has enabled the methods to be well-documented and of proven usefulness in the study of alternatives for design and decision-making in face of uncertainties. The paper presents a few case studies in different areas of geotechnical engineering and discusses the results that would have been obtained without the use of the risk approach. Special emphasis is given to dams and offshore structures, both piled and shallow foundations. The authors take a look at the reasons why the methods are not used to a greater extent in practice and make recommendations as to when and how one should uses such methods.

Risk and Reliability in Geotechnical Engineering

St. Louis, Missouri

Statistics, reliability analyses and risk estimates can be very useful decision-making tools in geotechnical problems. Yet the methods are little used in practice. The offshore and mining industry are at the forefront for the use of these approaches, having encouraged their use and sponsored research that has enabled the methods to be well-documented and of proven usefulness in the study of alternatives for design and decision-making in face of uncertainties. The paper presents a few case studies in different areas of geotechnical engineering and discusses the results that would have been obtained without the use of the risk approach. Special emphasis is given to dams and offshore structures, both piled and shallow foundations. The authors take a look at the reasons why the methods are not used to a greater extent in practice and make recommendations as to when and how one should uses such methods.
