Application of flow-round penetrometers for characterising soft sediments

点击翻译按钮获取中文摘要

Soft sediments present unique challenges in geotechnical engineering due to their sensitivity to disturbance during sampling. Strength measurement therefore relies on field tests, and novel penetrometers that force soil to flow around the probe have the potential for significantly improved accuracy compared with conventional cone penetrometers. The project aims to establish a definitive framework for interpreting results of field tests using flow-round penetrometers, through careful comparison of laboratory and field strength measurements. Applications of the work range from characterising deepwater sediments for offshore developments, to monitoring the strength of pastes in the mining and materials handling industries.
