Analysis on Testing Results of the Airport Runway Foundation Reinforced With Vibro-compaction Gravel Pile

Treatment effects of the airport runway foundation reinforced with vibrc-compation gravel pile are discussed, Bseed on data of drilling sampling tests and in situ tests, the variation rules of pore water pressure before and after the treatment are analyzed. Physical and mechanic property indexes of soil before and after the treatment are compared, and probability of sand seismic liquefaction are proposed. Some conclusions are given, which can provide reference for other engineering.
