Investigations into novel shallow penetrometers for fine-grained soils

Investigations into novel shallow penetrometers for fine-grained soils

This paper describes the initial evolution of two novel site investigation tools - shallow penetrometers - that are designed to measure the properties of surficial seabed soils, and in particular the axial resistance between pipelines and fine-grained soils. The shallow penetrometers are toroidal and hemispherical in shape, and are pushed vertically and rotated about the vertical axis. This design allows soil-interface shearing to be performed without the inconvenience of end effects. The paper describes numerical and centrifuge modelling results which show the resistance to purely vertical or torsional loading on undrained clay. The results of a cyclic torsional test using the toroidal penetrometer are shown, including detailed measurements of pore pressure build-up and dissipation. The new tools show promise and the results highlight the need to develop effective stress-based interpretation methods, to enhance the utility of these tools.

Abstract

This paper describes the initial evolution of two novel site investigation tools - shallow penetrometers - that are designed to measure the properties of surficial seabed soils, and in particular the axial resistance between pipelines and fine-grained soils. The shallow penetrometers are toroidal and hemispherical in shape, and are pushed vertically and rotated about the vertical axis. This design allows soil-interface shearing to be performed without the inconvenience of end effects. The paper describes numerical and centrifuge modelling results which show the resistance to purely vertical or torsional loading on undrained clay. The results of a cyclic torsional test using the toroidal penetrometer are shown, including detailed measurements of pore pressure build-up and dissipation. The new tools show promise and the results highlight the need to develop effective stress-based interpretation methods, to enhance the utility of these tools.
