Evaluation method for sand liquefaction of Hong Kong-Zhuhai-Macao Bridge based on CPTU tests

  • 摘要: 地震液化是引起地基失稳和上部结构损害的直接原因之一,因此,液化评价是土工抗震勘察中的重要内容。以港珠澳大桥岛隧工程为例,通过CPTU数据与标准贯入试验、剪切波速试验结果分析比较,一方面建立了可靠的CPTU数据与SPT、剪切波速的相关关系;另一方面利用CPTU液化判别方法,对岛隧砂土液化势进行了评估,并与SPT、剪切波速判别液化结果进行对比验证,得出基于CPTU液化判别法具有一定优势。研究结果可为类似重要工程勘察提供参考依据。
    Abstract: The earthquake liquefaction is one of the direct causes for unstable ground and damage of upper structure. Therefore, the liquefaction assessment is an important part of anti-seismic investigation in engineering. By taking the island and tunnel project of Hong Kong-Zhuhai-Macao Bridge as an example, the CPTU data is compared with the results of standard penetration tests and shear wave velocity tests. On one hand, the correlations between CPTU data and SPT, shear wave velocity are established. On the other hand, the sand liquefaction potential of the island tunnel is evaluated by the method of CPTU and compared with the liquefaction results of SPT and shear wave velocity. The results show that the liquefaction method of CPTU has certain advantages and may provide reference basis for similar engineering survey.
