The assessment and control of the geoenvironmental impact of the environmental qualities such as aikali and acid were presented. On the soil acidification caused by acid rain, negative influence on the engineering properties of the stabilized soil was experimentally clarified. The neutralization mechanism of the stabilized soil was summarized referring to the deplotion step of Ca^<2+>. The method of predicting neutralization of the stabilized soil ground was proposed. Alkali migradon characterisdcs from the stabilized soil were also investigated referring to the buffer ability of filtration layer. It is suggested from the experimental result that the batcn method ordinarily applied will overestimate the buffer ability. For the application of the stabilized soil to embankment, the minimum thickness of the filtration layer to prevent the alkali migration was calculated from the proposed paramotric analysis, and the importance of permeability and workability of the materials as well as the neutralization ahility were emphasized
