砂土在地震荷载作用下极易发生液化,液化土地基对建筑物造成的危害不可忽视,特别地在海洋这种复杂的环境条件下,带来的危害可能更大。本文首先介绍了砂土液化给人类带来的灾难,然后介绍饱和砂土液化的机理、影响因素和判别方法,其中重点介绍了现阶段海洋工程中国内外使用的液化判别方法,并以我国南海某平台场址为例加以说明。
砂土在地震荷載作用下極易髮生液化,液化土地基對建築物造成的危害不可忽視,特彆地在海洋這種複雜的環境條件下,帶來的危害可能更大。本文首先介紹瞭砂土液化給人類帶來的災難,然後介紹飽和砂土液化的機理、影響因素和判彆方法,其中重點介紹瞭現階段海洋工程中國內外使用的液化判彆方法,併以我國南海某平檯場阯為例加以說明。

The sandy soil is prone to be liquefied under seismic excitations, and the harm of liquefied soil foundation to the buildings is non-ignorable, particularly in the complex environment of marine conditions, the damage could be even greater. This paper firstly introduces the disasters that liquefaction bring to mankind, and then introduces the mechanism of liquefaction of saturated sand, influencing factors and identification methods, which focuses on the methods of liquefaction that used both at home and abroad in Ocean Engineering at this stage, and it is illustrated by the example of South China Sea platform.
