RIGID PIPE PROOF TESTING UNDER EXCESS OVERFILLS WITH VARYING BACKFILL PARAMETERS SECTION V (VOLUME I): DATA ANALYSIS BY NEUTRAL POINT METHOD (THEORY AND COMPUTER CODE)

A neutral point (elastic center) approach is used to develop a coded algorithm for the analysis of a rigid pipe embedded in a deep highway embankment. The code was used to develop plots of wall bending moments and thrusts, stresses in the reinforcing bars and concrete and wall displacements resulting from the applications of soil stresses in the embankment. Quasi-theoretical wall displacements and strains commensurate with these parameters have been compared (in other sections of this project report) with measured displacements and strains. The text includes algorithm derivations, flow charts, sample input and output and listings for the main program and the plotting program. (FHWA)
