Abstract:

Field testing and analyses of two culverts at Cross Canyon are described: a 96-in. prestressed-concrete functioning culvert under 200 ft of overfill and an 84-in. reinforced-concrete dummy culvert under a maximum 183-ft overfill in the same embankment. Eight instrumented and two noninstrumented zones in the dummy pipe and functional and unstressed control instrumented zones of the prestressed pipe were monitored during and after embankment construction to determine peripheral soil stresses, internal forces, and displacements. Correlations were established between quasi-theoretical and measured parameters (moments, thrusts, displacements, distress, etc.) with a programmed analysis. Some standard analytical tools (settlement ratio, finite element) were checked against observations, and relative costs of different construction modes were considered. Heger's recently developed criteria were checked against actual appearances of two of four distress modes. The programmed analysis was modified to predict these distress modes. Profiles of effective-density coefficients were established for various construction modes. The importance of designing for density distributions representative of contemplated construction models is emphasized. (Author)
