Lime Stabilization on Friant-Kern Canal
Since construction in the late 1940's, the Friant-Kern Canal has experienced cracking, sliding, and sloughing of the side slopes in areas of expansive clays in both the concrete-lined and earth-lined portions. In the early 1970's, Bureau of Reclamation designers decided to remove portions of the canal lining, flatten the slopes, and reline the canal using a compacted soil-lime mixture in an attempt to stabilize the slopes. The project added 4 percent (based on dry soil weight) granular quicklime to the soil. Laboratory tests on the compacted soil-lime mixture showed that (1) soil-lime was about 20 times stronger than the untreated clay, (2) the strength of the soil-lime increases with time, (3) the plasticity index of the natural soil was reduced from 40 to 10 or less after adding the lime, and (4) the compressive strength of the soil-lime was dependent on the compacted density.
