| 摘 要： | 港珠澳大桥隧道工程地震液化判别是为港珠澳大桥的抗震设计提供依据，是为大桥建设服务的。根据英国标准（BS规范），通过初判和详判，详判采用了SPT、CPTU、波速测试判别方法，分别对港珠澳大桥隧道工程砂土进行了液化判别。通过对不同方法得出的液化判别结果进行综合分析，确定砂土液化判别的最终结果，并提出处理措施。通过对液化判别的最终结果分析，并与国标液化判别结果对比分析，分析差异，总结规律，为珠江三角洲入海处砂土液化判别提供经验总结。

| Abstract: | The evaluation of liquefaction resistance for HZM bridge tunnel engineering is to provide the basic data for the bridge design. The criteria for evaluation of liquefaction resistance which accord with British Standard include preliminary criteria and detailed criteria. Criteria based on SPT, CPTU, wave velocity test are all used in detailed criteria. The results of a comprehensive analysis of liquefaction by different methods, determine the final results of evaluation of liquefaction resistance of sand, and propose treatment measures. We discover the laws and differences with the GB standard of the evaluation in the area of Pearl river delta on the sea and provide experience. |
