中文摘要：

在广州地铁工程砂土地震液化判别过程中，考虑了地铁结构与液化土层的相互作用。通过大量的现场实验、室内动三轴实验，总结了水平场地、区间、车站土层液化分布情况和液化特点；为了提高液化判别精度，进一步详细地对比和检验了现场和室内的判别结果，分析了液化土层与结构的空间相对位置以及结构对液化势的影响，所采用的多参数和多手段的液化判别技术为合理的抗液化设计提供帮助。

英文摘要：

In the process of evaluating seismic liquefaction of sandy soils for Guangzhou metro, the interactions between metro structures and soils are considered, and the distribution and eharaeteristics of liquefaetions are studied through numerous in-situ tests and tri-axial dynamic laboratory tests for soil layers in level greenfield, under metro running tunnel sections and stations, respectively. In order to improve the accuracy of the evaluation, results from in-situ tests and laboratory tests are compared, and the influence of structures on the potential of liquefaction is studied. The multi-parameter and multi-tool approach employed in this study may help improve the rational evaluation of seismic liquefaction of soils for metro constructions.
