PERMEABILITY AND PIPING IN FRACTURED ROCKS
Two discussions of the paper and the closure by the author are presented. The first discusser points out the need for research to develop criteria for placement of compacted soil, filter and transition materials against fractured rock. The second discusser questions the technique used in the study and points out the different failure mechanisms that could occur in the compacted fill without the fill material being eroded into the rock fractures. The author, in his closure, notes that it is doubtful whether the criteria used for gravel packs would be sufficient to present erosion of very fine particles from the compacted zone into fractures, since gravel packs customarily exclude fires. Other questions discussed and answered include the apparent anomaly between shim thickness and the maximum size of particles eroded in experiments, the need for conservatism when placing compacted soil against rock face with fracture traces, and the use of continuous concrete facing.
