RIGID PIPE PROOF TESTING UNDER EXCESS OVERFILLS WITH VARYING BACKFILL PARAMETERS: SECTION I (VOLUME 3): CONCLUSIONS AND RECOMMENDATIONS FOR IMPLEMENTATION-P/S PIPE

A 96-in.-(2,438-mm) diameter, prestressed concrete pipe with 23.5-in. (596-mm) thick walls embedded under a 200-ft (61-m) highway embankment, was instrumented and tested under the load of the overburden. An essentially unloaded control segment was also instrumented and subjected to a similar environment. Equations were developed and a computerized neutral point program was written to assess prestressed pipe behavior, and quasi-theoretical and observed parameters were compared after prototype strains had been corrected for creep and shrinkage strains indicated by the control zone. Excellent correlations were obtained, especially at the higher overfills. Recommendations are furnished for implementation.
