Development of a Settlement Profiling System to Assess MSW Compression Characteristics

Bachus, R, T. Zettler, and J. Fleming

A comprehensive assessment was performed of the primary and secondary waste compression characteristics of an existing 60-foot deep waste deposit.

To obtain in situ waste compression parameters, an instrumented 10.4-acre test fill was constructed, fully instrumented, and monitored over an approximately 6-month long time period. To compliment conventional surface and buried settlement plates, a horizontal settlement profiling system was developed to facilitate settlement evaluations at 1-foot horizontal intervals along four transects at the base of the test fill. This paper focuses on the development of the settlement profiler and provides a discussion of the test results.
