Application of flow-round penetrometers for characterising soft sediments

在岩土工程中，软土对采样过程中的扰动非常敏感，这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，与传统的锥形渗透仪相比，迫使土壤在探头周围流动的新型渗透仪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现场强度测量结果，为使用流轮渗透仪解释现场测试结果建立一个明确的框架。这项工作的应用范围从近海开发的深水沉积物特征，到采矿和材料搬运行业中的浆体强度监测。

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.
