RIGID PIPE PROOF TESTING UNDER EXCESS OVERFILLS WITH VARYING BACKFILL PARAMETERS SECTION VII VOLUME 2: FINITE ELEMENT ANALYSIS
A finite element analysis of an 84-inch (2134-mm), reinforced concrete culvert, under approximately 190 ft (58 m) of embankment, made with full consideration for asymmetric canyon boundaries (see Section VII, Volume 1), is repeated, for the five zones previously analyzed, using a greatly simplified, symmetric, rectangular mesh. The objective of this additional work, which was requested by the FHWA, is to establish comparisons between parameters significantly affecting culvert behavior, as predicted by the complex and simplified analyses. Consideration of full boundary conditions requires pre-survey potential culvert sites, which may make such analyses prohibitively expensive and time-consuming. The simplified analysis and comparative predictions are discussed in this volume. (Author)
