Test method for axial force at pile top in centrifugal model tests on pile-net composite foundation

More Information
  • Received Date: April 28, 2024
  • The pile-net composite foundation is a common soft soil reinforcement measurement. In order to analyze the pile-soil stress ratio, it is necessary to measure the axial force at the pile top and the soil pressure between piles in the centrifugal model tests. The mini-earth pressure cells have been widely used in the centrifugal model test, but there is no commonly accepted mini-axial force sensor. In this study, a special method is developed for testing the axial force at the top of piles in the centrifugal model tests by using pile caps. Great linearity is shown through the calibration data. The effects of the proposed method are verified by the pile-soil stress ratio results from the centrifugal model test and numerical analysis of a pile-net composite foundation.
