中文摘要：

从砾性土的定义出发，回顾了砾性土从被认为不会液化到其液化现象引起工程师关注的研究历程及国内外研究进展。总结了含砾量、相对密度等因素对砾性土抗液化能力影响关系的研究现状。介绍了国际上对砾性土场地液化判别的研究成果及各种主流方法的优势与不足；分析了剪切波速方法应用于砾性土场地液化判别的可行性。研究认为：砾性土的液化现象正逐渐被科学界及工程界接受；含砾量对砾性土抗液化能力的影响研究仍然存在较大矛盾，相对密度等影响砂土抗液化能力的因素同样影响砾性土抗液化能力；砂土场地应用的标准贯人、静力触探等液化判别方法不适用于砾性土场地，国际上发展了基于动力触探和贝克尔贯入试验的液化判别方法；剪切波速判别方法在砾性土场地的液化判别中具有优势和潜力，是今后研究的方向之一。

英文摘要：

From the definition of the gravelly soils, the research progress of gravelly soils liquefaction resistance andprediction is reviewed, when the phenomenon of gravelly soils liquefaction is gradually accepted by engineers. Theinfluence factors as gravel contents and relative density on gravelly soil liquefaction are summarized. Prevailinggravelly soil liquefaction prediction methods are introduced. Moreover, the feasibility of shear wave velocity to eval-uate gravelly sites was analyzed. The research results indicate： the results about gravel contents influencing the re-sistance are still not unity qualitatively; other influence factors almost having the same effect between the sands andgravelly soils; CDPT is an effective method on liquefaction prediction on gravelly sites, although SPT and CPT can-not be used and BPT method is not used in China; shear wave velocity is a potential indicator that could be furtherstudied on gravelly site liquefaction prediction.
