Review of T-bar full-flow penetration testing in offshore engineering

  • 摘要: 随着近年来中国海洋开发的不断深入发展,海洋工程设计时对于海洋土承载能力及循环荷载效应的勘测提出了更高的要求。由于从深水地区回收土样进行室内试验的难度和成本过高,海洋岩土工程设计参数的确定往往依赖于现场原位测试技术。回顾了海洋静力触探技术的发展历程,介绍了一种适用于海相软土的全流触探仪。总结了国内外学者对全流触探仪的理论及试验研究,包括贯入阻力与软土不排水抗剪强度之间的关系、循环贯入试验对重塑土特性的评价以及通过数值模拟得出T型全流触探仪的阻力系数等。最后,对全流触探仪发展提出了展望。
    Abstract: With the further development of marine exploration in China in recent years, higher requirements are put forward for the capacity of the soil and cyclic loading effect for the offshore engineering. Due to the difficulty and high cost of laboratory tests which the samples are collected from the deep water, marine geotechnical engineering often relies on the in-situ testing technology. The development of offshore CPT technology is reviewed, and a kind of full-flow penetrometer is introduced for marine soft soil. The theoretical and experimental researches on the full-flow penetrometers of domestic and foreign scholars are summarized, including the relationship between penetration resistance and soft soil undrained shear, evaluation of the characteristics of remolded soil from cyclic penetration tests and numerical simulations of resistance coefficient of T-bar full-flow penetrometers. Finally, some suggestions are put forward for the development of full-flow penetrometers.
