摘要由于难以从海上获得高质量的土壤样品，并且需要大量的实验室测试和工程判断，因此需要越来越多地依赖于原位贯入仪测试，以获得连续的贯入阻力曲线。本文报道了一种直接从单层粘土和钙质粉土中全流贯入计（T-bar）试验的连续阻力曲线估计马铃薯渗透阻力的框架。该框架主要通过离心机试验数据进行验证，并辅以一些报道的现场数据。
AbstractDifficulties in obtaining high-quality soil samples from offshore sites and heavy involvement of lab testing and engineering judgment have necessitated increasing reliance on in situ penetrometer tests, giving continuous penetration resistance profiles. This paper reports a framework for estimating spudcan penetration resistance directly from continuous resistance profile of a full-flow penetrometer (T-bar) test in single-layer clays and calcareous silts. The framework was validated chiefly against centrifuge test data, supplemented by some reported field data.
