RIGID PIPE PROOF TESTING UNDER EXCESS OVERFILLS WITH VARYING BACKFILL PARAMETERS. SECTION I: INTRODUCTION, HISTORICAL BACKGROUND, PROJECT DESCRIPTION AND INSTRUMENTATION

A grossly underdesigned, 84-in. (213-cm) reinforced concrete, dummy culvert was placed in the same highway embankment with a functional, 96-in. (244-cm), prestressed concrete pipe. Maximum overfills were 183 ft (56 M) and 200 ft (61 m), respectively. Backfill parameters were varied in ten zones of the dummy pipe. Eight zones in the R/C pipe and one in the P/C pipe were instrumented with soil stress-meters, strain gauges and displacement-measuring devices. An unloaded segment of the P/C pipe was also instrumented as a control segment. Instrumentation was monitored at frequent intervals during fill construction. Section I of the report details the historical background, objectives and description of the research project, and details of instrumentation. A second volume of Section I will provide conclusions and recommendations for implementation resulting from studies of the dummy culvert, while a third volume will provide the same for the prestressed pipe. A fourth volume of Section I will describe conclusions from finite element analyses of the Cross Canyon Embankment-culvert continuum. (FHWA)
