DYNAMIC COMPACTION OF SANITARY LANDFILLS WITH HIGH WATER TABLES. FINAL REPORT

Dynamic Compaction was selected to stabilize two test sections in highly compressible sanitary landfills with high ground water tables. This method consisted of free fall dropping a 20 ton weight from 70 to 80 feet high on predetermined grid points. Both test sections were instrumented and monitored. The results indicated 2 to 4 hundred percent improvements in ground stiffness which exceeded the expectations. This method was immediately implemented on a similar sanitary landfill along the future I-76 in northwest Denver. About 8.5 acres of surface area was treated and an additional site has been scheduled to be treated in the fall of 1984.
