An optimisation strategy for evaluating modified Cam clay parameters using self-boring pressuremeter test data
An optimisation strategy for evaluating modified Cam clay parameters using self-boring pressuremeter test data
This paper presents an efficient, practical and automated strategy for deriving Modified Cam Clay parameters from undrained self-boring pressuremeter (SBPM) data. A mixed approach involving a parametric sweep and numerical optimisation is used, with a focus on parameter groups that dominate the Modified Cam Clay response in undrained cavity expansion. The proposed technique is illustrated using data from SBPM tests carried out in soft estuarine clay. The resulting parameters are used to back analyse large scale foundation load tests and are shown to provide an excellent match to the measured foundation response.

Abstract
This paper presents an efficient, practical and automated strategy for deriving Modified Cam Clay parameters from undrained self-boring pressuremeter (SBPM) data. A mixed approach involving a parametric sweep and numerical optimisation is used, with a focus on parameter groups that dominate the Modified Cam Clay response in undrained cavity expansion. The proposed technique is illustrated using data from SBPM tests carried out in soft estuarine clay. The resulting parameters are used to back analyse large scale foundation load tests and are shown to provide an excellent match to the measured foundation response.
