    • 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.
