在实践中,有几种标准可用于评估土壤的液化敏感性。例如所谓的中国标准和较新的标准,如Andrews和Martin (2000), Seed等人(2003),Bray和sanio(2006),以及Boulanger和Idriss(2006)。许多这些标准使用不同的土壤指标,行为状态和限制值,这使得在实践中使用各种标准有时令人困惑。本文的目的是通过解决实践中经常被问到的三个问题,为使用最近和常用的三个液化敏感性标准(seed等人,2003年,Bray和Sancio, 2006年,以及Boulanger和Idriss, 2006年)提供实际考虑:(1)什么土壤可以使用液化敏感性标准?(2)液化敏感性标准提供了什么信息?(3)液化敏感性标准的最佳用途是什么?
Several criteria are available in practice to assess the liquefaction susceptibility of soils. Examples are the so-called Chinese Criteria and more recent criteria, such as Andrews and Martin (2000), Seed et al. (2003), Bray and Sancio (2006), and Boulanger and Idriss (2006). Many of these criteria utilize different soil indices, behavioral states, and limiting values, which make the use of the various criteria in practice confusing at times. The purpose of this paper is to provide practical considerations in the use of three of the most recent and commonly used liquefaction susceptibility criteria—Seed et al. 2003, Bray and Sancio 2006, and Boulanger and Idriss 2006—by addressing three questions often asked in practice: (1) What soils can liquefaction susceptibility criteria be used? (2) What information is provided by liquefaction susceptibility criteria? (3) What is the best use of liquefaction susceptibility criteria?
