贝克渗透试验作为一种测量砾石土壤液化潜力的原位技术，在北美得到了越来越多的应用。此测试涉及使用大型动态贯入仪，并结合了打桩和标准贯入测试的元素。尽管它的应用越来越广泛，但它仍然是一种非标准测试，存在许多不确定因素，包括驱动能量和套管摩擦。本文介绍了该试验的发展、应用以及在液化潜力评价中的建议。
The Becker Penetration Test has seen increased use in North America as an in situ technique for measuring the liquefaction potential of gravelly soils. This test involves the use of a large dynamic penetrometer and incorporates elements of both pile driving and the Standard Penetration Test. Despite its increasing use, it remains a non-standard test with many uncertainties involving driving energy and casing friction. This paper describes the development of the test, its application, and recommendation for its use in the assessment of liquefaction potential.
