A Study of the Sand Bank Stability in Liquefying Tests with the Dynamic Tri-axial Apparatus

The phenomena of failure appeared usually for the sand shell of dams and embankments during severe earthquakes.The liquefying test with a dynamic tri-axial apparatus is one of the usual methods to perform.Here, except discussing the drainage and relative density conditions in tests, the decrease of total stress resistance of different sands during liquefaction is presented so as to examine nearly the stability of sand banks.
