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.

软沉积物在取样过程中对扰动的敏感性给岩土工程带来了独特的挑战。 因此，强度测量依赖于现场测试，并且与传统的锥形流量计相比，迫使土壤围绕探头流动的新型流量计具有显著提高精度的潜力。 该项目旨在通过仔细比较实验室和场强测量值，建立一个明确的框架，用于解释使用流动流量计进行的现场测试结果。 这项工作的应用范围从表征近海开发的深水沉积物到监测采矿和材料处理行业中的膏体强度。
