Compressional Creep Test of High Embankment Settlement

  • Publish Date: 25 Dec 2004
  • By taking the embankment, with a height of 104 m, of Jiuzhai-Huanglong airport as an example, similar conditions of compressional creep tests simulating the high embankment using filling material of sandy gravel were investigated. The research results show that the compressional creep tests with rigid boundary conditions have favorable similarity with the large-scale high embankment in a depression, and their stress states are very close to the same, but the amount of settlement obtained from the compressional creep tests with rigid boundary conditions are less than that of in-situ monitoring. Furthermore, the degree of initial compaction of the coarse grain filling material controls its compressional characteristics. When the degree of initial compaction is 97.4%, the process of compaction settlement shows a logarithmic characteristic, and when the degree of initial compactio is above 98. 7%, the process of compaction settlement indicates a linear characteristic.
