- Abstract:
- :Desaturation of ground by air injection attracts considerable attention in recent years as an innovative cost effective technique for liquefaction countermeasure.This paper describes an in-situ air injection test which aimed to verify effectiveness of the use of higher air injection pressures to desaturate very wide zone from a single air injector.In the test,air was injected in liquefiable foundation soils immediately below a highway embankment.Observations revealed that the soil around the injector was desaturated effectively and the zone of influence extended more than 9 m from the injector.This radius was about 5 times larger than that achieved in the past test,leading to a dramatic reduction in execution cost.
