Abstract

The complete title of Session two on case histories of unexpected behavior of foundations made reference to unusual soils, diverse environments, a wide range of foundation test methods and structures ranging from historic monuments to tall buildings and towers. In attempting to provide a narrative to the myriad papers submitted which match the session themes we must consider whether unanticipated foundation behavior can ever be described as unexpected. In every project Geotechnical Engineers are charged with predicting the response of structures composed of or built on naturally heterogeneous material. The process (which is not linear) consists of many stages including site investigation, design, and construction and monitoring. If undertaken properly, uncertainties should reduce as the process advances and there should be sufficient feedback and flexibility to allow knowledge gained to influence other stages of the process. Each project therefore is a case history in which knowledge gained can help to develop the empirical knowledge of the designer. Case histories are therefore an integral part of the education and development of all Geotechnical Engineers. Our report groups the papers submitted into four sections which can be roughly aligned to stages in the design process, namely; investigation, design, installation and performance. Many papers naturally contain contributions which address multiple headings and our classification, though subjective was to assign papers in the area where we felt the major contribution lay. Of the 32 papers submitted for this session, 5 deal primarily with investigation, 10 are focused on design, 5 consider the effects of installation and unsurprisingly, given the conference theme the vast majority (12 papers) considers foundation performance.

General Report – Session 2

Chicago, Illinois

The complete title of Session two on case histories of unexpected behavior of foundations made reference to unusual soils, diverse environments, a wide range of foundation test methods and structures ranging from historic monuments to tall buildings and towers. In attempting to provide a narrative to the myriad papers submitted which match the session themes we must consider whether unanticipated foundation behavior can ever be described as unexpected. In every project Geotechnical Engineers are charged with predicting the response of structures composed of or built on naturally heterogeneous material. The process (which is not linear) consists of many stages including site investigation, design, and construction and monitoring. If undertaken properly, uncertainties should reduce as the process advances and there should be sufficient feedback and flexibility to allow knowledge gained to influence other stages of the process. Each project therefore is a case history in which knowledge gained can help to develop the empirical knowledge of the designer. Case histories are therefore an integral part of the education and development of all Geotechnical Engineers. Our report groups the papers submitted into four sections which can be roughly aligned to stages in the design process, namely; investigation, design, installation and performance. Many papers naturally contain contributions which address multiple headings and our classification, though subjective was to assign papers in the area where we felt the major contribution lay. Of the 32 papers submitted for this session, 5 deal primarily with investigation, 10 are focused on design, 5 consider the effects of installation and unsurprisingly, given the conference theme the vast majority (12 papers) considers foundation performance.
