RIGID PIPE PROOF TESTING UNDER EXCESS OVERFILLS WITH VARYING BACKFILL PARAMETERS: SECTION VII VOLUME 3: NEUTRAL POINT ANALYSIS USING FINITE ELEMENT AND OBSERVED TRACTIONS

Normal and tangential soil tractions acting on the external periphery of an 84-in (2134-mm), reinforced concrete pipe at Cross Canyon have been measured experimentally (see Section II) and derived by finite element analyses using: 1) a full mesh considering canyon wall boundary conditions and presence of a second pipe (see Section VII, Volume 1); and, 2) a greatly simplified, symmetrical, rectangular mesh with no second pipe (see Section VII, Volume 2). In this volume are discussed results of inputting to the neutral point analysis (see Section V, Volume 1) tractions derived from field measurements and from the two levels of finite element analysis. Various output parameters and maximum pipe stresses are compared among the three outputs for relative validity. (Author)
