Rigid Pipe Proof Testing Under Excess Overfills with Varying Backfill Parameters. Section 7. (Volume 2): Finite Element Analysis

摘要

A finite element analysis of an 84-inch 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 is to establish comparisons between parameters significantly affecting culvert behavior, as predicted by the complex and simplified analyses. The simplified analysis and comparative predictions are discussed in this volume.
