ABSTRACT

Correction of an existing landslide or the prevention of a pending landslide is a function of a reduction in the driving forces or an increase in the available resisting forces. This chapter presents a methodology involving back analysis of the slope and the use of piles to remediate the landslide. Landslides are so varied in type and size, and in most instances, so dependent upon special local circumstances, that for a given landslide problem there is more than one method of prevention or correction that can be successfully applied. The success of each measure depends, to a large extent, on the degree to which the specific soil and groundwater conditions are prudently recognized in an investigation and incorporated in design. There is considerable experimental evidence to show that the Mohr failure envelope exhibits significant curvature for many different types of soil and compacted rockfill.
