A Survey and Evaluation of Remedial Measures for Earth Slope Stabilization.

摘要

The results of a literature survey undertaken to identify remedial measures which have been used to stabilize earth slopes are presented. In this review attention is directed to specific case histories and field conditions where the remedial measures were actually used. The remedial measures reviewed include drainage of surface and subsurface water,restraint structures,elimination and avoidance of the slide area, benching and slope flattening as well as a number of special procedures including electroosmosis,thermal treatment and addition of stabilizing admixtures. Of the procedures reviewed drainage of surface and subsurface water appears to be the most widely and successfully used technique. However,the success of each measure depends to a large degree on the specific soil and groundwater conditions for the slope and the degree to which these are correctly recognized in an investigation and design.
