THE UNDERSTANDING OF CONTINUOUS FLIGHT AUGER PILING, ITS MONITORING AND CONTROL. (INCLUDES APPENDIX)

Demonstrates factors which influence both construction reliability and load bearing performance. Suggests that the most detrimental effects are often to be found in cohesionless soil of less than medium density. Emphasizes the need for electronic monitoring of installation and proposes a model of the construction process. It is also suggested that it is essential in future development to automate the process. (Original abstract-amended)
