Abstract
A methodology was developed to evaluate causation of a complex landslide that occurred in Franciscan Complex melange during the winter of 1996-1997 in San Mateo County, California. Conventional back-analysis methods to evaluate shear strength parameters were insufficient because the basal failure plane traversed three materials (fill, block-poor melange, and block-rich melange). Instead, using field observations of landslide kinematics, review of available subsurface data, and previous experience with Franciscan melange, a methodology was developed that incorporates the location of critical failure surfaces generated by random search routines in PCSTABL5M as an additional constraint. The methodology was employed to evaluate the relative effects of various destabilizing modifications to the slope.
