CONSTRUCTION TECHNOLOGY OF REPLACED-BACKFILLING CLAY TO REINFORCE SWELLING ROCK SLOPE

There is the replaced-backfilling clay treatment test region,from SY0+208～SY0+268,one part of the Luwangfen test Region of middle-route of South-to-North Water Division Project. , in which the excavated heavy silt loam is dealt as the replace-backfilling clay,then is used to reinforce the swelling slope by vibration bumping roller.During the compaction test,the construction technology and related control standard of replaced-backfilling clay treatment is studied.It is proved that the application of this treatment to reinforce the swelling slope,which is provided as the reference for the treatment of similar slope in the middle-route of South-to-North Water Division Project.
