Abstract

The washout resistance of foamed treated soil which is made of dredged slurry and is cast underwater is studied. The washout resistance test is newly developed and the following conclusions are obtained by a series of the test.<br>1) In a washout resistance test of the casting velocity control type, the density of suspended solid (SS) of water, pH value of water and the strength of soil after curing can be indexes of the washout resistance.<br>2) The results of the washout resistance test shows that, as for the foam treated soil used in this study, the mixing proportion of 180-290mm flow value and the casting velocity less than 80cm/sec are recommended to prevent the washout.<br>2) Foam treated soil of 15, 000m³ were cast underwater for backfilling of quaywall in Kobe Port. By using the result of washout resistance test, the observed values of SS and pH were small and the properties of the ground was uniform.
