CHEMICAL STABILIZATION OF AN ACTIVE LANDSLIDE

An adaptation of drilled-lime stabilization was tried on an active landslide on the north city limits of Des Moines. The slide was in poorly compacted fill containing about 30% montmorillonitic clay, and resting on an eroded shale surface sloping about 15-20%. The project appears to have been successful, indicated by physical and chemical soil tests and measurements on the houses; meanwhile adjacent untreated or drained properties continued to fail. Cost of the new process depends primarily on the depth of drilling to the shear zone. On this particular slide the cost of several thousand dollars was considerably less than any of the other attempted remedial measures, none of which were as successful.
