Paper Title:
Concealed Karst Cavity’s Treatment in Kunming New Airport
  Abstract

The different treatments, such as the sleeve valve grouting method and the high pressure grouting with sleeve valve grouting method is adopted according to the concealed cavity in Kunming new airport. Test results show that: (1) after treatment, the equivalent shearing wave velocity of whole soil layer of NO.GR1 is higher and the physical property of foundation is improved than before, meanwhile although a great deal of concrete are used in the engineering, there is only a little cement paste found between 2.2m~18.0m during the core-drilling test, which means the test is not successful. (2) The shearing velocity of improved layer is higher in NO.GR2, the shearing velocity of other layers is lower than before treatment, which means the high pressure grouting with sleeve valve grouting method is feasible method to treat the concealed karst cavity.
