Abstract:

The dredger fill foundation of a diversion canal cannot be directly used because of the low ground bearing capacity and potential earthquake liquefaction. On the basis of meeting the demands of anti-liquefaction, the sand-pile replacement ratio was determined according to the Japanese technical standard and liquefaction safety factor of foundation in combination with in-situ test data. And then, the related stability calculation parameters were obtained by composite foundation method, the stability of diversion canal slope reinforced by sand compaction piles and vibro-replacement stone column was also analyzed by limit equilibrium method. At last, the reasonable foundation treatment measures were provided through comparison of different reinforcement schemes.

Key words: diversion canal, foundation liquefaction, foundation treatment, slope stability
